FIELD: combined processing of copper-nickel cobalt-containing sulfide materials at different copper-to-nickel ratio at obtaining anode copper, high-grade matte and waste slag.
SUBSTANCE: proposed method includes pyro-metallurgical processing of copper-nickel cobalt-containing sulfide materials at different copper-to-nickel ratio accompanied by producing anode copper and nickel slags. High-grade matte is obtained both directly in flash smelting furnace at processing materials at low copper-to-nickel ratio and in converters by processing metallized electric furnace matte together with nickel slag. Proposed method makes it possible to reduce cost of production of high-grade matte and losses of non-ferrous and precious metals, to facilitate procedure of utilization of sulfur dioxide from waste gases and enhancing utilization.
EFFECT: enhanced efficiency; increased volumes of processing nickel slag.
