An Updated Review of Toxicity Effect of the Rare Earth ...

Rare earth elements are relatively abundant in Earth’s crust, with critical qualities to the device performance. The reuse and recycling of rare earth elements through different technologies can minimize impacts on the environment; however, there is insufficient data about their biological, bioaccumulation, and health effects.

Effects of Simulated Rare Earth Recycling Wastewaters on ...

Increasing rare earth element (REE) supplies by recycling and expanded ore processing will result in generation of new wastewaters. In some cases, disposal to a sewage treatment plant may be favored, but plant performance must be maintained. To assess the potential effects of such wastewaters on biological treatment, model nitrifying organisms Nitrosomonas europaea and Nitrobacter winogradskyi ...

Recycling and its effects on joint production systems and ...

Jul 01, 2018  In this paper, we present a production model to analyze what effects the introduction of an Nd-Fe-B recycling scheme would have on the global rare earth market. The model confirms and quantifies the market effects reported in the literature, i.e. that the utilization of Nd-Fe-B recycling potentials would not jeopardize the supply of joint REE ...

Rare earth: health and environment effects health effects ...

If rare earth resources are not mined and developed properly, not only does it result in economic losses for countries, but it also does great harm to global ecotopes, especially during the processes of mining, refining and recycling, which may result in serious environmental consequences. A particular hazard is mildly radioactive slurry ...

RARE EARTH ELEMENTS: A REVIEW OF PRODUCTION,

Rare earth elements (REEs) are a group of 15 chemical elements in the periodic table, specifically the lanthanides. Two other elements, scandium and yttrium, have a similar physiochemistry to the lanthanides, are commonly found in the same mineral assemblages, and are often referred to as REEs. REEs have not been mined in the United States for about 20 years, and prior to that time, the amount ...

Why rare earth recycling is rare – and what we can do ...

Recycling rare earth elements isn’t as easy as recycling glass or plastic — there are challenges at nearly every level. For one thing, the elements are present in small amounts in things like cell phones. As parts get smaller, so do the amounts of material used. In a touch screen, for example, the elements are distributed throughout the ...

Rare-earth element - Wikipedia

The rare-earth elements, also called the rare-earth metals or (in context) rare-earth oxides, or the lanthanides (though yttrium and scandium are usually included as rare-earths) are a set of 17 nearly indistinguishable lustrous silvery-white soft heavy metals. Scandium and yttrium are considered rare-earth elements because they tend to occur in the same ore deposits as the lanthanides and ...

Life Cycle Impact of Rare Earth Elements

The diverse properties of rare earth elements have seen broad and growing applications in clean energy technologies, hybrid vehicles, pollution control, optics, refrigeration, and so on. This study presents a “cradle-to-gate” life cycle assessment of the energy use, resource depletion, and global warming potential resulting from the production of rare earth elements (REEs) using the Bayan ...

May 10, 2019  Sales of electronics were up 6% year-on-year. Neodynium made up almost 40% of rare earth demand in 2017. The metal is expected to see an ‘impressive’ surge in demand in the near future.. A positive development noted by the analysts is that the recycling of rare earth metals is ‘slowly overcoming’ existing demand-supply issues as well as ensuring a steady supply of critical rare earth ...

Recycling of Rare Earth Elements

Any development of an effective process for rare earth (RE) recycling has become more and more challenging, especially in recent years. Since 2011, when commodity prices of REs had met their all-time maximum, prices have dropped rapidly by more than 90 %. An economic process able to offset these fluctuations has to take unconventional methods into account beside well-known strategies like acid ...
