Rare elements, including rare earth metals (REM), germanium and gallium are widely used in various fields of science technology. Germanium the semiconductor industry, rare-earth structural materials for aviation space, as well nuclear energy. The sufficiency with own raw is a strategic issue producers metal materials. Despite vast reserves deposits Russia, they far from developed infrastructures characterized by complex enrichment
