METHOD FOR FLOTATION OF FLUORITE-CONTAINING NON-SULFIDE ORES

摘要

FIELD: beneficiation of minerals. SUBSTANCE: method for flotation fluorite-containing non-sulfide ores includes grinding ore in the presence of modifying agent, subsequent pulp conditioning with depressing agent, medium regulator, and fat/acid collector, and generation of foam product from fluorite concentrate. Soda/sulfate mixture is added as modifying and regulating agent. The mixture is produced in the process of thermal treatment of technological wastes from caprolactam industry and comprises sodium salts of inorganic acids. EFFECT: waste processing. 2 tbl
