These roles are further discussed in chapter three. Each metal is unique yet Just like several other rare earth metals, it is primarily found in the mineral there are some similarities between them. In addition, it is evident that these elements have many similarities amongst them. These seventeen metals make up the center of the periodic table and are essential to our modern world, with its reliance on electronic devices.

Many questions regarding these seventeen metals remain, such as where these rare earth metals come from. The next chapter will try to answer this question and provide a more thorough understanding of these metals. Written By Samira Sunderji Introduction Rare earth metals hold a unique place among the elements on the periodic table as they serve as integral components of various electronic devices and clean energy resources Elliot, Although these rare metals are very much alike chemically and physically, their magnetic properties, temperature resistance, and resistance to corrosion are what sets them apart from each other Elliot, Regardless, they are essential to our modern lives.

While rare earth metals play an important role in a number of scientific discov- eries and applications, their origins and histories are equally as important to understand. This information proves to be useful to create a framework for scientists and companies to understand rare earth metals, so that their use can be expanded.

These metals, as you will see throughout this book, hold significant scientific and geopolitical importance History and Future of Rare Earth Elements, The status and power dynamics between countries continue to shift in regard to rare earth metal production. Therefore, sustainable usually found mixed together with one another or with radioactive elements, practices and technologies for rare earth metal extractions are being developed such as uranium and thorium Long et al.

Consequently, most of the and implemented. While the previous chapter detailed the properties of all 17 rare earth metals, this chapter will elaborate on the rarity of these elements, their origins, How are Rare Earth Metals Created? There are a number of plausible explanations as to how these elements formed. Nucleosynthesis As stated earlier, rare earth metals are composed of 17 metallic elements.

An atom is the basic unit of a chemical element. Protons positively charged On the periodic table, these elements have the atomic numbers 21, 39, and 57 particles and neutrons neutrally charged particles are the key components through to 71 History and Future of Rare Earth Elements, Thus, nucleosynthesis is a process by which number of these elements describe the number of protons and neutrons of new atomic nuclei are constructed from existing protons and neutrons.

Nuclear fission earth metals in creating power dynamics will be thoroughly discussed in the occurs with heavier elements when the electromagnetic forces pushing the coming chapters.

The fission of heavy elements on the periodic table is an exothermic reaction, a What is the Future of Rare Earth Metals? As stated previously, rare earth elements are likely to remain an important part of our future. The Please note that the countries listed below were the top 10 countries that role of rare earth metals in clean energy efforts and curbing greenhouse-gas mined the most rare earth metals according to data collected by the United emissions is especially important to avoid the devastating consequences of States Geological Survey as of Pistilli, Ongoing processes to decrease the production of internal combustion cars and increase the production of electric vehicles will also Rare earth metal production continues to rise across the globe to meet the increase the demand for rare earth metals.

The growth of wind farms as a demand created by the heightened popularity of renewable energy and newer method of sustainable energy will continue to drive the demand for neodym- technologies. Rare earth metals such as neodymium and praseodymium serve ium and dysprosium, which are used in wind turbine motors. The salt-based systems used mines and building processing plants across the globe. While the ideas behind to recover rare earth metals are highly stable which allows for the recovery of these proposals may seem far-fetched and unattainable at this moment in elements such as neodymium without the generation of side products that time, they could become economically viable and a reality if a large increase can affect the purity of the element Pozo-Gonzalo, Unlike previously in rare earth metal demand increases prices, or if global governments collab- reported methods, IFM can recover neodymium metal without a tempera- orate and subsidize the costs of production, or if climate change becomes so ture-controlled atmosphere, and can work at temperatures lower than oC devastating that we are forced to take action.

Though generally unfamiliar compared to its popular elemen- tal counterparts such as hydrogen and helium , the rare earth metals are an essential component of hundreds of devices. The versatility of rare earth metals establishes their technological, environmental, economic, and political importance. Although the elements are generally similar in their geochemical properties, certain characteristics, as well as their individual concentrations, are by no means equal to each other.

While this chapter has debunked myths in regard to the rarity of rare earth metals, it has also described the origins and creation story of rare earth metals. Processes of supernova nucleosynthesis and nuclear fission shed light as to how these elements were created and have been embedded within the interior of our planet.

Moreover, this chapter has touched upon topics of great importance concerning the future of rare earth metal use and productions. Mining processes for rare earth metals are not safe for the environment and are not sustainable. With the hope of becoming more environmentally-friendly and safe, continuous research is necessary to push the boundaries of the unknown and collectively work towards sustainable methods of rare earth metal extraction and overall use in society. The following chapter will focus on the individuals behind the discovery of rare earth metals, and will shed light on how their research and knowledge translated into scientific achievements that allow for us to use rare earth metals today.

Written By Si Cong Sam Zhang Introduction Many people know that some of the elements in the periodic table are named after places, people, astronomical objects, or simply the minerals in which they are commonly found. So one would expect the United States to top the charts in terms of the number of elements named after it with berkelium, californium, tennessine and americium.

But, in fact, the champion is Sweden with holmium named after Stockholm and 4 other rare earth elements named after a sleepy little village on a small island a 40 minute drive away from downtown Stockholm. How the village of Ytterby came to be the place with the most elements named after it is a story that begins long before the invention of the periodic table by Dmitri Mendeleev or even before the first list of modern chemical elements were written down by Antoine Lavoisier.

This chapter will tell the story of the discovery of rare-earth metals, and it begins in the village of Ytterby. Berzelius and Wilhelm Hisinger. During this visit, he founder of modern chemistry. Berzelius would go on to discover selenium, and his students would also discover lithium, lanthanum, A sample of this dense black mineral with attached feldspar was eventually and vanadium in his laboratory.

While the Swedish pair is now credited with sent to the Finnish chemist, mineralogist, and physicist Johan Gadolin in the the discovery, the German chemist Martin Heinrich Klaproth, known for the Royal Academy of Turku then the University of Abo in While he was never able to isolate the unknown elements found within this sample, he was the first to conduct By , yttrium and cerium were identified as yttria and ceria respectively. Therefore, he is today most the first chapter, while rare earth elements are not particularly rare, they are often credited with the discovery of the first rare earth metals.

Because of this property, even though the samples of ceria and yttria together contained all the rare A colleague of Gadolin, Anders Gustaf Ekeberg was able to obtain a larger earth elements, it was impossible for the elements to be further separated sample of the unknown black mineral without feldspar.

He was able to confirm until more than three decades later the discovery of Gadolin and improve upon the original results. Mosander was the first person to be able to separate rare earth metals aluminum oxide, and his sample contained He from each other. Following in the for the discovery of rare earth metals would go to Gadolin, Ekeberg would footsteps of his teacher, he was able to further purify the samples of ceria and leave his name in history by discovering tantalum, which was also from this yttria.

In , he isolated metallic cerium. Although the sample was impure, same mine in Ytterby.

But Mosander was eventually successful, when in he was able Following the pattern established by other researchers, L. Nilson would to separate what he believed to be a new element: didymium. It was named then go on to isolate scandia from ytterbia. This is because, unknown to Mosander, much like the previous supposed pure elements and despite his best efforts at separation, didymium is still a Several other alleged rare earth element discoveries were also made in and mixture of rare earth elements.

Despite his failure in this regard, Mosander the years shortly after, many were cases of mistaken identity, but some were was still able to generate many breakthroughs in the discovery of rare earth also genuine new rare earth elements. The American chemist J. Lawrence Smith metals.

He found that the ceria sample contained an insoluble portion, and was able to isolate an element from samarskite which he named mosandrum in soluble portions of lanthana and didymia. But Delafontaine reported that mosandrum did not exist and was actually terbia.

Delafontaine similar techniques. In , he showed that yttria with the ceria, lanthana working with samarskite was able to isolate a supposed element which he and didymia removed contained at least three more earths. The properties named philippium after Philippe Plantamour. In addition to philippium, Delafontaine was Freiherr von Welsbach Freiherr is a nobility similar to Baron, Freiherr von able to identify another element, named decipium, which is now thought to Welsbach can roughly be translated to Baron of Welsbach.

Auer is his family have been misidentified samarium The Discovery and Naming of the Rare name, and Carl is the first name. Auer was a favourite student of the great German chemist Robert Bunsen After the removal of ytterbia and scandia, the leftover erbia was further inventor of the bunsen burner , and was greatly interested in inorganic studied by the Swedish chemist Per Teodor Cleve.

He noted that the atomic chemistry and rare earth minerals in particular. Under the supervision of weight of erbium after the removal was not constant. With experimenta- Bunsen, who had extensive knowledge regarding didymium, Auer began his tion, he was able to purify erbia into 3 components: erbia, holmia and thulia. Auer named his two new pium previously noted by Delafontaine, therefore they were likely the same elements neodymia new didymia , and praseodymia green didymia. Returning to the twin element didymia, as far back as , there had been proposals by Marignac that didymia was not an element but a mix of many In , Lecoq identified an additional element from his sample of didymium, elements.

Lecoq named this source. So in , Lecoq reacted didymium with ammonium hydroxide and element gadolinium after the gadolinite in which this element can be found. He was able to isolate In the same year, Lecoq was also able to separate holmium into two different this precipitate and find the spectrum of this new substance was different elements, holmia and dysprosia via fractional precipitation.

Because the two from that of the rest of didymia. Using this information he deduced that this elements are so similar in properties, it took more than 30 attempts to isolate was a new element and named it samaria after the mineral samarskite from dysprosia from holmia. Com, n. In addition to discovering many rare Even after the removal of samarium, it was still thought that didymium was earth metals, Lecoq also discovered gallium, naming it after the Latin name a mixture of more than one element.

Brauner was able to identify two groups of absorption bands within didym- ium, one in the blue region and another in the yellow region. A legendary figure in the field of spectroscopy at the time, removed was still a mixture of two elements very close in properties. Lecoq despite efforts from multiple chemists, it would take until for didym- noticed a faint line in the spectrum of samarium in In , he conducted a series of fractionations of samarium which yielded a new element that he named europium.

Unfortunately, he died soon after his discovery in and was unable to conduct more thorough studies of europium. The last of the discoveries were made independently by the French chemist Georges Urbain as well as Auer at around the same time in Urbain was able to separate ytterbia into two elements by repeated fractional crystallization.

He named the components neoytterbia and lutecia. However, neoytterbia would later be changed back to ytterbia and lutecia to lutetia. At last, over a period of more than one century, every rare earth metal has been discovered from the original ceria and yttria. The ability for rare earth metals to blend into each other seamlessly played an integral role in the discovery of these elements, as the elements were able to be isolated gradually based on how close they are in properties to each other.

Now that we know the history behind the discovery of these rare earth metals, in the next chapter, we will find out the important role these metals play in our everyday life. Written By Anusha Mappanasingam Introduction Rare earth metals are a significant component of modern life. In chapter 1, we were presented with the 17 different types of rare earth metals.

In chapters 2 and 3, we discussed the origins of the rare earth metals and the people who discovered them. From what we know so far into this book, we have come to understand how relevant rare earth metals are in our lives. Rare earth metals make up a crucial component of the periodic table of elements: they include atomic numbers , making up Group IIIA Henderson, They also play an important role as components of electronics.

When considering this, it can be surprising to see that many people are not familiar with rare earth metals. Take yourself back to your high school days: you probably came across the periodic table of elements in your science classes. In these classes, many of us are only taught the first 20 elements, from hydrogen to calcium. This can give off the impression that the rest of the elements are insignificant; many of us will continue the rest of our lives without ever truly understanding how significant these rare earth metals are.

This chapter will aim to enforce this understanding by presenting the various roles that rare earth metals can have in our world. This will be done by considering their role in geology, geochemistry, and space. While these will be the focuses of this chapter, we will take some time to consider some roles that rare earth metals can have in other areas.

One thing that is common with these indirect methods is that they all come with Role in Geology and Geochemistry problems that can make their use detrimental to their initial purpose Frey, To comprehend the role that rare earth metals have in geology and geochemis- However, there is a single direct approach that can be used instead try, it is first important to understand geology and geochemistry themselves.

It is processes like the direct approach that have allowed geologists to earth, as well as the organisms that inhabit the planet What is Geology? It is apparent that the subjects of variation amongst light rare earth elements LREE than amongst heavy rare geology and geochemistry are closely related and that the study of rare earth earth elements HREE Frey, The details of this abundance are not metals has a significant contribution to each.

In this section, we will consider relevant to this chapter—this is brief ly discussed in chapter 6. Rather, it is this contribution by breaking down the role of rare earth metals in geology the implications of its presence in the mantle that are of primary concern.

This section will cover rare earth metals Rare earth metals can help with understanding upper mantle processes and their role in rocks, and radioisotopes and geochronology. Some of these include using rare earth metals to understand Elements, n. Most of these rare earth metals are found in very minute quan- and document partial melting processes, the range of melting that occurs, tities inside various types of rock such as igneous, alkaline and carbonatite.

While their presence in various mentioned can not only provide a direct outlook into the heterogeneous nature rocks is crucial in our attempt to understand the role that rare earth metals of the elemental composition of the upper mantle, but it can also provide have in our world, it is their participation in the formation of many rocks that insight into the heterogeneity of the mantle by helping geologists determine requires the utmost attention as this role is vital to many geological cycles.

One example of this is the identification of LREE enrichment We will begin by looking at the role of rare earth metals in the upper mantle of occurring in both the ocean and continental mantle Frey, While these the earth. Although in-depth discussions of these are outside the into this role any further, we need to first understand the specifics that allow scope of this chapter, it is enough to know that they exist.

More details on the environmental implications can be found in chapter 9. Conclusion In conclusion, this chapter discussed the role of rare earth metals in the world.

Firstly, we looked at the role of rare earth metals in geology and geochemistry. This was done by considering the role that these metals have in rocks and radioisotopes and geochronology. Then we looked at the role of rare earth metals in space. Lastly, we brief ly discussed the other roles that rare earth metals might have in other fields.

The many ways in which rare earth metals are associated with our world are obvious. In the next chapter, we will discuss the importance of rare earth metals. Written By Rishi Mohan Introduction The rare earth metals are a group of 17 elements consisting of scandium, yttrium and the 15 elements contained in the lanthanide series.

However, due to the important role of rare earth metals, the benefits of mining them greatly outweigh the negatives. In this chapter, the importance of rare earth metals will be assessed. This will be done by first determining how rare earth metals impact the daily lives of a typical individual living in the western hemisphere. Next, the role of rare earth metals for the purpose of innovation will be examined.

Finally, the importance of rare earth metals in established power dynamics will be addressed. The Importance of Rare Earth Metals in Our Daily Lives The 17 metallic elements that comprise the rare earth metals, are integral components to many of the electronic devices you use on a daily basis King, The reason this is the case is because rare earth metals possess unique properties that make them desirable for a wide range of potential applications Kirkpatrick, Rare earth metals have an intrinsic resistance to high levels of heat, strong magnetic properties and act as an excellent conductor of electricity Kirkpatrick, However, these devices would not be nearly as efficient or light as the current iterations that contain The Integral Role of Rare Earth Metals in Our Daily Electronic Devices rare earth metals Butters, This is because electronic devices, communication, Bluetooth connectivity and barcode scanning among others like a smartphone, require a constant magnetic f lux Gutf leisch et al.

Those electronic mine how iPhone users utilize their smart device. They found that, on average, devices utilize rare earth metals in a similar way. In the paragraph above, various iPhone functions that are to information is at an all-time high thanks to integration of rare earth metals enabled through the inclusion of rare earth metals were mentioned.

The Importance of Rare Earth Metals Regarding Innovation Rare earth metals are an integral component in the functionality of these From the previous section you saw how important rare earth metals are to our medical imaging and diagnostic tools Ascenzi et al.

Due to the unique daily lives. However, beyond that, the implementation of rare earth metals properties of rare earth metals, they are the optimal material to serve as is vital to innovation. Scintillators are of systems and tools. Sticking with our previous example, think about how materials that are able to convert high energy radiation or particles into light much the design and capabilities of the current iPhone has improved upon that can be detected by an electronic sensor Ascenzi et al.

Scintillators that of the original iPhone in such a short period of time. There are two are responsible for converting the emitted radiation so that it is readable by primary drivers for innovation. The first is innovation through inspiration. In this way, rare earth metals This would be akin to the addition of a feature to an iPhone that was not play an invaluable role in the detection of medical diseases. The second driver of innovation is necessity.

This would be equivalent to the The Integral Role of Rare Earth Metals in Emission-Free Innovations material of the latest iPhone iteration being so brittle that it bends when it is Scientists have long been sounding the alarm regarding fossil fuels and climate put in your pocket.

In this scenario, the design team would need to improve change. Nolt, This problem is another that can be solved by innovation upon the structural composition in order to make the iPhone a feasible option due to necessity. One potential solution to reduce the output of emissions is for consumers. Ultimately, innovation is borne out of a need to eliminate an to transition from fossil fuel powered vehicles to ones that are powered exclu- obstacle or problem.

In the upcoming section, we will examine two sectors sively by electric batteries. Doing this would significantly reduce the amount related to the survival of humankind to illustrate how rare earth metals are of harmful emissions produced by human actions. Like in previous cases, used as vehicles for innovation.

The Integral Role of Rare Earth Metals in Medical Innovations The application of rare earth metals in the automotive industry is not a novel Those in the field of medicine aim to discover, understand and treat diseases idea. Currently, rare earth metals are utilized in the motors of most vehicles, that arise in patients. Due to this fact, innovative approaches are often both fossil fuel and electric ones, because they allow the motor to be perma- required.

One department of medicine that has seen a large amount of inno- nently magnetized Gutf leisch et al. Nickel metal-hydride batteries, vation recently is the realm of diagnostics. China has done. China dominates the rare earth metal industry, having the Nickel metal-hydride batteries confer many environmental and functional rest of the world rely on them to supply this commodity Mancheri, Sund- benefits.

This topic is discussed in greater detail within Chapter In earlier sections some of the Another way to reduce the amount of harmful emissions is to switch to greener technological uses of rare earth metals popularized by the United States were sources of energy. Whilst hydropower and bioenergy are the front runners in referenced. However, one that has yet to be mentioned is the importance of that department, solar and wind energy are expected to grow rapidly within rare earth metals in regards to national defence.

The rare earth metal yttrium the coming years Pavel et al. In , wind energy accounted for a little for example is used in militaristic equipment like radar systems Jha, The International Energy Agency anticipates that the quantity of energy such as being lightweight and reliable Jha, Regardless of whether you sourced from wind turbines will increase until Pavel et al.

Wind weigh power based on economic or militaristic might, it is hard to argue turbines require the inclusion of rare earth metals, specifically: neodymium, against the fact that rare earth metals play an important role in establishing praseodymium, dysprosium and terbium for their unique magnetic properties a power dynamic.

Pavel et al. These rare earth metals play an integral role in facilitating the function of the permanent magnet synchronous generator contained in Conclusion wind turbines Pavel et al. Therefore, rare earth metals are undoubtedly In summary, this chapter examined the importance of rare earth metals.

Despite The unique abilities of rare earth metals, such as their intrinsic resistance to their importance to the green energy industry, it is important to note that high levels of heat, strong magnetic properties and their electric conductivity the process of extracting these rare earth metals can have severe detrimental make them desirable components for a wide array of potential applications.

To learn more about how the extraction of rare earth Some of these applications include the electronic devices we use on a daily metals impacts the planet, refer to Chapter 9. Without the integration of rare earth metals in these devices, they would be robbed of The Role of Rare Earth Metals in Creating Power Dynamics the convenience, efficiency and full colour display that popularized them in The previous subsections have made it apparent that rare earth metals are the first place.

Rare earth metals are a vehicle of innovation. Medical diag- important because they impact our lives in various ways. Therefore, it stands nostics and clean energy are two sectors that have experienced a large level to reason that the nation that produces the largest supply of rare earth metals of innovations thanks to rare earth metals.

Finally, the sway that rare earth would distinguish themselves as a global economic power. This is exactly what metals have in determining power dynamics was also explored. On the other hand, the United States utilizes rare earth metals in militaristic applications to strengthen their prowess on the battlefield.

The next chapter examines the current status of rare earth metals. Written By Joonsoo Sean Lyeo Introduction Due to their importance in the manufacturing of high technology products, rare earth metals are highly sought after by businesses and governments alike Campbell, In recent years, this demand for rare earth metals has grown exponentially Campbell, This chapter will be dedicated to discussing the current status of rare earth metals in terms of their abundance, their strategic value, and their future role in the global supply chain.

In fact, rare earth metals are just as common, if not more common, than most other types of metals used commercially Campbell, For instance, the rare earth metal yttrium is about as abundant as lithium; a key ingredient in rechargeable batteries Zepf, Even dysprosium, a rare earth metal that was only isolated History of Global Rare Earth Metal Production in the s, is twice as abundant as gold and eight times as abundant as Historical trends in the global production of rare earth metals can be divided platinum; both of which are commonly used to make false teeth Zepf, Is it some be discussed below.

For instance, while some metals, such as Naumov, It was characterized by the extraction of rare earth metals gold or copper, can be found in naturally occurring concentrated deposits— from heavy sand deposits, especially those containing high concentrations of such as veins, nuggets, and rock matrices—rare earth metals are unlikely to monazite minerals; hence the name Naumov, While monazite sands accumulate in any significant concentration Campbell, As a result, it often had a relatively low rare earth metal content, these deposits could be is extraordinarily rare to find naturally occurring rare earth metals in their processed using relatively simple methods, thus allowing for significant rare pure, uncombined form—never mind on a scale that could be considered earth metal production at the expense of time and manpower Naumov, commercially accessible Campbell, As a result, in most commercial The United States was one of the first countries to engage in large-scale settings, rare earth metals are typically collected as a byproduct of more monazite sand mining with the intent of yielding commercial quantities of plentiful and easily accessible resources Campbell, For instance, rare rare earth metals, beginning with an pilot project based in North Carolina earth metals are often collected as a byproduct of the mining of mineral-rich Naumov, Note that despite being one of the Campbell, While yttrium is indeed about as abundant as lithium, the 7, tonnes of yttrium mined each year is dwarfed by the 36, tonnes of lith- The second of these periods, the Mountain Pass Phase, began in the s ium mined in the same period Zepf, Similarly, the 19, tonnes of Naumov, As the global demand for rare earth metals increased, spurred neodymium and 23, tonnes of lanthanum mined each year almost seem by the invention and subsequent mass production of coloured television negligible when compared to the 1.

Finally, in terms of annual production, the tonnes of carbonatite rock—containing a number of rare earth metal compounds—in dysprosium produced worldwide lags behind the tonnes of gold produced Mountain Pass, California Zepf, For a twenty-year-long period, lasting in Ghana alone—keep in mind that Ghana is only the seventh-largest producer from to , the Mountain Pass Mine was single-handedly responsible of gold ore Holmes, In other words, This status quo would soon come to an end.

This single deposit is estimated to contain approximately 36 trillion metal production elsewhere Campbell, The Mountain of its activity at the Bayan Obo Mining District through the sale of iron ore, Pass Mine was ultimately unable to recover from this setback and, after a allowing them to continually operate the site regardless of f luctuations in the period of steady decline, eventually ceased operations in , leaving the market price of rare earth metals Campbell, As a result, the Bayan Obo Bayan Obo Mining District with an iron grip on the rare earth metal market Mining District can afford to stockpile rare earth metals to be processed at a Castor, China has continued to tighten its hold over the market, of the Rare Earths Trade Dispute—in which China limited its rare owing much of its success to a combination of environmental passiveness earth metal export quotas, causing a sharp hike in the market prices of rare and market economics Campbell, Japan claimed meters below the surface, contained high concentrations of rare that this was a calculated ploy by the Chinese government, implemented as earth metals such as gadolinium, cerium, europium, and yttrium Kato et al.

With great excitement, the research team announced that they were disputed waters around the Senkaku Islands Campbell, The aforementioned Mountain Pass Mine, for instance, Kato et al. Aside from the revitalization of the Moun- In , this statement was supplemented by the findings of a second research tain Pass Mine, investments have also been directed towards emerging rare team from the University of Tokyo Takaya et al.

This has culminated in a substantial increase in that the sediments in the delineated area, covering an area of about square the volume of rare earth metal production outside of China, with the total kilometres, contained enough yttrium to meet the global demand for the next annual production increasing from 40 megatonnes to 98 megatonnes Paulick 62 years Takaya et al.

Thus far, this chapter has primarily focused on the extraction of rare earth The results were promising, prompting the researchers to consider how this metals from terrestrial sources—i. In their from the ground. While this may seem like the most intuitive way of accessing final report, the team expressed their optimism regarding the potential imple- rare earth metals, recent innovations have allowed us to gauge new possi- mentation of deep-sea mining projects in the near future Takaya et al.

This subsection will be dedicated Asteroid Mining to discussing some of the emerging technologies allowing for unconventional In light of the growing discussion around the commercialization of space methods of rare earth metal production. Fries, Conclusion For instance, some recent innovations have allowed for the recycling of the rare This chapter was dedicated to discussing the status of rare earth metals in earth metals used to manufacture permanent magnets; the type of magnets several different contexts.

Generally speaking, the recycling of rare earth metals from permanent distinction between geological abundance and commercially relevant abundance. Both processes have their own advantages and disadvantages. Finally, this chapter concluded with an For instance, the first process—the recycling of rare earth metals as blended analysis of how recent and emerging technological innovations may allow for metals—offers the advantage of being less energy-intensive, but comes with the production of rare earth metals through previously untapped means.

As a result, the rare earth metals recycled through this refer to the next chapter. Written By Anittha Mappanasingam Introduction Rare earth metals play a hidden, yet vital part in our daily life. Whether we are able to recognize it or not, rare earth metals are the foundation for many of the things that we deem important today, such as electronics, space, and the economy.

Because of its essential applications, the production of it is inev- itable, hence the processes must be carefully monitored to ensure that they are occurring in the most efficient and effective way possible.

The production of rare-earth metals involves three steps—mining of the rare earth metals, separation of the valuable ore from other waste compounds, and purification of the ore to separate out the metal Science of Rare Earth Elements, Although these steps are fairly similar when processing most other metals, with rare earth metals, it typically involves an additional stage—separating rare earth metals from each other Science of Rare Earth Elements, This last step is often incredibly difficult and costly, creating the need to use complex separation techniques, some of which will be discussed as we get further into the chapter Science of Rare Earth Elements, In order to understand if the processes being used to produce rare earth metals are ideal, we must first understand the science behind these various techniques.

As a result, this chapter will go into the science behind product, mixed product, or individual rare earth salt Xie et al. The various processes used in the separation of rare earth metal production, latter purpose, producing individual rare earth salts, is extremely difficult and the science behind the analytical methods used to produce rare earth because the elements that make up these metals usually all display similar metals.

Specifically, the science behind separation techniques, such as solvent chemical properties Science of Rare Earth Elements, These rare earth extraction, chromatographic separation and adsorption, will be reviewed. Because of this, solvent extraction is typically used in order to obtain higher concentrations of specific Science in Separation metals, as a previously used technique, ion-exchange chromatography, was Separating rare earth metals is the most important part of the production only able to produce smaller amounts of higher concentrations Science of of rare earth metals.

The scientific basis underlying the separation process Rare Earth Elements, ; Xie et al. The impact of these processes on the environment is undeniable as we will learn more in chapter 9. So, researchers and producers After the solvent-solute mixture has been extracted from the raw ore, this are always trying to find new ways to create more efficient and affordable method typically involves the addition of an extractant to an organic solvent, in methods to extract rare earth metals.

An extractant is discussing three key techniques that are normally used to separate rare earth a compound used to extract a substance, in this case, rare earth metals, from a metals—solvent extraction, chromatographic separations, and adsorption. So when the extractant is mixed with the organic solvent and Solvent extraction is the most common method used to separate rare earth is in contact with the solvent containing rare earth metal components, the rare metals Science of Rare Earth Elements, However, this occurs at extremely slow rates Science of Rare Earth nuclear and food industry Anderson, n.

Brief ly, solvent extraction involves Elements, Eric Schelter, the director of the Center for the Sustainable separating compounds based on their solubility Schaller, Although his description reinforces that this process is extremely inefficient, The solvent extraction process is fairly similar when applied to rare earth this is only the case when viewing it from a single extraction, and over the metals. The specificities of the solvent extraction method used may vary years, chemical engineers have been able to develop solvent extraction into based on a couple of factors, such as the composition of rare earth metals an effective process Science of Rare Earth Elements, The process begins by separating the rare earth metals from the contaminated water, called Chromatographic Separations leachate Xie et al.
