The article gives a review of the current technologies of rare earth metals processing at operating plants in Russia (Lovozersky deposit) and abroad (Bayan OBO (China), Mountain Pass (USA), Mount Weld (Australia), etc. The analysis of the rare earth metal mining projects in the world shows that generally rare earth metal processing and concentration uses conventional technologies of mechanical preparation — flotation, gravity, magnetic separation, electric separation, etc., and their combinations. Some mineral processing projects involve hydrometallurgical methods, which is conditioned by features of material constitution of the raw material. The authors discuss basic processes and technologies of preparing rare earth metals concentrates with production of various compounds and individual rare earth metals. Particular attention is paid to the rare earth metals industry branch in Russia, with suggested lines of growth of the raw material base and rare earth metals production, including extraction of rare earth metals in processing of apatite concentrates.

The authors debate on the basic tasks and solutions in the framework of the subprogram “Development of the Rare Metals and Rare Earth Metals Industry” of the Russia’s government program “Industrial Development and Competitive Recovery over the Period to 2020”.
