method of processing raw materials containing non-ferrous metals and iron

摘要

the invention relates to metallurgy industry, mainly to the metallurgy of nickel and cobalt, and deals with how to obtain the liquid metal in the per u0435u0440u0430u0431u043eu0442u043au0435 oxidized u043cu0435u0442u0430u043bu043bu0441u043eu0434u0435u0440u0436u0430u0449u0435u0433u043e natural raw materials, and man-made materials.the way includes the file in u043eu043au0438u0441u043bu0438u0442u0435u043bu044cu043du0443u044e zone u0434u0432u0443u0445u0437u043eu043du043du043eu0439 u0448u043bu0430u043au043eu0432u044bu0439 furnace in steel is composed of a raw material u0444u043bu044eu0441u043eu0432, liquid or solid u043fu0435u0440u0435u0440u0430u0431u0430u0442u044bu0432u0430u0435u043cu043eu0433 of the slag, u0443u0433u043bu0435u0440u043eu0434u0441u043eu0434u0435u0440u0436u0430u0449u0435u0433u043e material and the oxygen in the u043au0438u0441u043bu043eu0440u043eu0434u0441u043eu0434u0435u0440u0436u0430u0449u0435u043c u0434u0443u0442u044cu0435 in quantities necessary for the complete combustion of the carbon allocation heat.then the lead smelting is with the formation of liquid slag produced in the recovery area, which serves u0443u0433u043bu0435u0440u043eu0434u0441u043eu0434u0435u0440u0436u0430u0449u0438u0439 material u043au0438u0441u043bu043eu0440u043eu0434u0441u043eu0434u0435u0440u0436 u0430u0449u0435u0435 u0434u0443u0442u044cu0435 and additional u0444u043bu044eu0441u044b in quantities necessary for the recovery of metals and metal oxides derived by phase compensation heat costs.the technical result is to increase the extraction of metals and improve the separation of u0448u043bu0430u043au043eu0432u043eu0439 and metal baths. in the proposed method, the way is the prototype) for drying and tube source (often wet) raw materials used derogating gases.the proposed method differs from the prototype, the cross-section of the stanchion upper oxidizing and recovery zones and zone and the drying oven u043au0430u043bu0438u0432u0430u043du0438u044f feedstock may be round, square or other shapes, with the given ratio of the cross sectional area of the node to the total space docking and oxidizing zones and regenerative furnacesas well as the given ratio of floor furnace recovery zone to melting.
