Abstract:
The metallurgy of copper and other heavy non-ferrous metals is the leading link in the domestic non-ferrous metallurgy. The share of heavy non-ferrous metals in Uzbekistan accounts for a significant part of the gross output of the industry. The value of copper is increasing from year to year, especially in connection with the rapid development of energy, electronics, mechanical engineering, aviation, space and nuclear technology. This paper will consider the technology for reducing the loss of copper with slags during smelting processes. Numerous parameters affect the copper content in slags, of which the following should be considered the most important: preparation of the charge, parameters of the technological mode of smelting, physicochemical properties of melts, design of units, organization of work, etc. It is very difficult to give an unambiguous assessment of the influence of all parameters acting separately or in aggregate, and is hardly possible at all. In this regard, we will try to assess individual process parameters from the point of view of their influence on the depletion indicators and the possibility of changing their values ??in real metallurgical smelting.
