The aim of the study was to analyze the technical and economic evaluation of complex processing of iron and steel industry waste - dump clinker Waelz achisay zinc ores by electrothermal melting in an electric arc furnace , to produce ferrosilicon and collective fumes for non-ferrous metals. During the processing of complex electro clinker Waelz in ferrosilicon recovered iron and silicon, and in the collective fumes non-ferrous metals extracted zinc, cadmium and lead, the resulting slag is crushed into gravel, used in road construction, as well as in the construction industry as a placeholder. To determine the complexity of the technology of complex processing blade clinker Waelz achisay zinc ores by electrothermal melting in an electric arc furnace, to produce ferrosilicon and collective fumes for non-ferrous metals was carried out technical and economic assessment of the technology that can extract valuable metals from waste and reduce human pressure on the natural environment of the region.
