FIELD: metallurgy.
SUBSTANCE: proposed method comprises locating of concentrate into converter and its oxidative smelting. First, matte is poured into converter to blow it with coal-air mix at coal consumption of 500 kg per ton of matte at coal-to-air ratio of 0.35 kg/m3. Concentrate is loaded on fused matte surface to blow it with air enriched with oxygen to 25 vol. % to complete smelting of concentrate. Quartz and lime flux are loaded to proceed with blowing to produce the slag and matter rich in copper, both are, now, discharged by 70% to resume melt blowing with coal-air mix.
EFFECT: simplified process.
