Selected Issues of Mischmetal and Other Rare Earth Metal Obtaining

Abstract

Rare earth metals forming the group of lanthanides as well as scandium, yttrium, lanthanum and usually they are referred to in brief REE (Rare Earth Metals).As a critical to the EU economy, 20 raw mineral of major economic importance were discriminated, therein RRE. The elements limit the development of modern advanced technologies. The choice of rational process for the preparation of rare earth elements is related to their physical and chemical properties. The present article was devoted some technologies for mischmetal obtaining and other rare earth metals. There have been presented trends in progress in technologies of mischmetal and other REE obtaining.
