(Environmentally, rare-earth mining is generally low-impact. Extraction is chemical, not thermal no fuel-hungry furnaces and the chemicals involved are easily neutralized or contained: common acids and bases, water and oils. The chief concern is the trace amounts of mildly radioactive elements that occur in all rare-earth deposits.
The era of Rare Earth mining at Mountain pass was born. The Mine That Powered Modernity. In some ways, rare earth metals is a misnomer. The rare earth elements are chemical elements as well, 17 elements in all, which often exist embedded in
Overview. The rare earth elements (REEs) are comprised of the lanthanide elements plus scandium and yttrium, which have similar physical properties and are often found in the same ores and deposits.
Once the rare-earth-containing ore is made into a powder, it is chemically conditioned and mixed with water. The specks with the highest rare-earth content float to the top. After a few rounds of this process, the resulting solution is thickened and filtered to form a rare-earth concentrate.
Chinas six major suppliers decision to stockpile on 5,000 tons of nine types of rare earth metals this year, and governments plans to create a separate national reserve by buying 15,000 tonnes from them.
A rare-earth element (REE) or rare-earth metal (REM), as defined by IUPAC, is one of a set of seventeen chemical elements in the periodic table, specifically the fifteen lanthanides, as well as scandium and yttrium.
