Abstract
Rare earth metals have been made from rare earth compounds which were prepared from rare earth ore concentrates through successive processes such as leaching(i.e. extraction of rare earth elements to liquid media), separation, purification, precipitation. Here, process for treating monazite and bastnasite ore concentrates were briefly reviewed, and metallothermic reduction and fused salt electrolysis methods were introduced as the extraction technologies for rare earth metals.
