Rare Earth Elements Extraction Process. Selective extraction and recovery of rare earth metals from waste. The rare earth elements occur at very low concentrations in most so rare earths today across the world are separated using one process, and that's called solvent extraction.
Rare earth elements (ree) are a group of seventeen chemical elements that occur together in the periodic table, 15 lanthanides ( z=57 through 71), scandium and yttrium.
A physical enrichment step and a chemical enrichment/extraction step. In nuclear technology, the solvent extraction is an important step for recovery of rare earth materials, purification, radionuclide production, and preparation of nuclear reactor materials. Rare earth elements are used in electronics, but increase in demand could lead to low supply. The availability of rare earth elements from primary resources has come into question in the last two decades.
