Improvement of smelting of sulphids copper raw material in molten bath with new view to extraction on metals-companions

There the purpose are to develop the scientific and practical recommendations for the apparatus-engineering styling of gas-motion path of Vanyukov smelting, to study the distribution of metals-companions according to the smelting products and to study the concentrating in the industiral products. The condensation mechanisms for the lead, for the rhenium and for the arsenic under the catching conditions of coarse dusts in the waste boiler and under the precipitation conditions of fine dusts in the dry electric filter have been studied; the optimum concentration of oxygen at the inlet of dedusting system of Vanyukov smelting furnaces has been determined; the process requirements for the reburning of hydrocarbon components and of element sulphur under the arch of Vanyukov smelting have been substantiated. The work results and the work recommendations have been used during the learning process to apply and during the improvement process of Vanyukov smelting system at the "Balkhashmed" PA. The rational reburning system of hydrocarbon components and of sulphur under the arch of Vanyukov smelting furnace has been introduced. The recommendations have been used at the learning to apply of Vanyukov smelting system at the "Balkhashmed" PA. The formation principles of dedusting system have been took account at the designing of Vanyukov smelting at the Central Ural Copper-Smelting Works. The results may be used at the smelting of copper-zinc concentrates and of copper-lead mattesAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
