Extraction metallurgy is a branch of metallurgical engineering, which studies the process and method of extracting metals from natural ore deposits. The field is a material science that covers all aspects of ore type, washing, concentration, separation, chemical processes, and extraction of pure metals and their alloying for various applications, sometimes directly as finished products, but more often, further work is required to achieve the given properties to suit the application. The company's production capacity is 55000 tons / year, and there are more than 60 varieties of products, which are mainly used for flotation of copper, lead, zinc, gold, silver, nickel, cobalt and other non-ferrous metal sulfide ores, oxide ores, rare earth metal ores, cobalt molybdenum ores, copper zinc ores, tungsten fine slimes, iron concentrates, etc., and has national and municipal technology research and development centers.
