Abstract

FIELD: nonferrous metallurgy. SUBSTANCE: invention relates to known methods of processing tungsten- and molybdenum-containing raw materials based on mechanically treating these minerals, which results in increased solubility of the latter in acids and alkalis, and intensification of leaching bauxite and hydroargillite by UV and X-ray irradiation. The two methods are characterized with low efficiency, especially with optically low transparent raw material because of essentially nonuniform treatment of raw material using above named methods. EFFECT: improved procedure.
