FIELD: metallurgy.
SUBSTANCE: invention relates to nonferrous metallurgy. Method of processing lead production semi-products containing lead, copper and zinc includes loading the said intermediate products into a shaft furnace, together with coke as a reducing agent, sulphidizer and quartz ore as flux and their melting with supply of oxygen-containing blast to produce black lead, copper matte and zinc-containing slag. As the sulphidizer concentrate or ore containing lead, copper and zinc are used, herewith the ratio of silica content to zinc content in a loading is 1.2-1.6, ratio of copper content to sulphur content in a loading is 0.7-1.2, lead-to-copper ratio in a loading makes 1.5-3.0.
EFFECT: higher extraction of nonferrous metals, as well as reduction of coke consumption for melting are provided.
