The article presents the results of analyzes to study the possibility of extracting valuable components from industrial waste from non-ferrous metallurgy. Of particular interest for the production of new types of products, in particular lead and additional extraction of precious metals (gold, silver), are the fine converter dust of the copper smelting plant of Almalyk MMC, the accumulation of which necessitated the search for technical solutions for their processing. Dust captured in electrostatic precipitators mainly contains metal sulphates, which violate the autogenousness of the melt and contribute to a decrease in the process temperature.
