Lead extraction and zinc extraction from slags of copper-smelting production by reducing-sulphide method

There the study objects are the converter slags of copper-smelting production. The purpose is to develop the depleting process of slags from the copper-smelting production, which contain the lead and the zinc, in the electric furnace of direct current with the following processing of industrial products and of wastes from the metallurgical production. The data about the properties of matte-slag melts including the metallized polymetallic mattes have been obtained; the change mechanism of sulphur to the gas at the reducing-sulphide treatment with the taking part of metallic iron has been determined. The depleting process of slags in the electric furnace of direct current by the reducing-sulphide method has been developed. The depleting process of slags, which contain the copper, the lead and the zinc, has been proposed. The semi-industrial tests have been performed. The application field is the metallurgy of heavy non-ferrous metalsAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
