摘要

The invention relates to non-ferrous metallurgy, mainly to devices for processing pulverized lead- and zinc-containing raw material which also could contain copper and precious metals. The aim of said invention is to increase the direct extraction of lead into impure metal and the unit specific performance. The inventive unit for processing pulverized lead- and zinc-containing raw material comprises a vertical melting chamber which has a rectangular cross-section and is provided with a burner device, a gas cooler shaft, a baffle provided with water-cooling copper elements, which separates the melting chamber from the gas cooler shaft, an electric furnace separated from the melting chamber by the baffle provided with water-cooling copper elements, a caisson ring, a device for tapping a melting product, a bottom, wherein the difference quotient of the lower edges of the baffles to a distance between the roof of the melting chamber and the lower edge of the baffle separating the electric furnace from the melting chamber ranges from 0.15 to 0.29, whilst the distance ratio between the lower edge of said baffle and the bottom to the difference of the levels of the lower edges of the baffles ranges from 1.25 to 2.10.
