FIELD: metallurgy.
SUBSTANCE: invention refers to procedure for depletion of solid copper-zinc slag. The procedure consists in supply of charge containing solid copper-zinc slag and carbonic reducer at weight ratio of slag to solid carbonic reducer 1: (0.06-0.1) into heated furnace. Also charge in the heated furnace is blasted with oxygen containing oxidant by means of upper not-immersed blast; consumption of oxygen-containing oxidant is determined by contents of oxygen in it from condition of 60-110 kg per ton of slag. Further there is produced a rich with copper phase and zinc is transferred into a gas phase.
EFFECT: simplification of process of solid copper-zinc slag depletion.
