Rare earth ore goes through these steps hundreds and hundreds of times, and for each new mining location, the concentration of the acids used has to be recalculated in order to target the specific impurities in the soil. To top it off, the whole process produces any number of nasty chemical byproducts and is radioactive. Rare Earth Response

The elements are also important to national ...
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. Although relatively
More than 5 million tons of apatite phosphogypsum, a waste derived from the production of phosphoric acid, have been tipped on the waste tip of the Wizów Chemical Plant (Poland). This waste contains Rare Earth Elements (REE) which are on the list of 'critical' raw materials in the EU and other countries.
PSI of Andover, Mass., has been awarded a research contract from the Department of Energy to develop and demonstrate a pilot scale plant to economically produce salable REYSc (rare earth element-rich concentrates including yttrium and scandium) and commercially viable co-products from coal ash using environmentally safe, and high-yield physical and chemical enrichment processes.
