Samadov, Sh.T. Khojiev, B.A. Jalolov, N.M. Muzafarova Abstract: Uzbekistan is one of the countries with a highly developed metallurgical industry. The formation of this industry was facilitated by rich mineral resources and the availability of energy sources. In the bowels of Uzbekistan there are deposits of almost all elements of the periodic table, and many of these reserves are already in commercial exploitation. At present, the mining and metallurgical industry of the republic faces a whole range of complex problems. This is, first of all, the all-round depletion of rich and easily discovered ore deposits, increased requirements for environmental protection, and an increase in demand for non-ferrous metals, including copper and related elements. An urgent problem is to increase the complexity of the use of raw materials, the utilization of all valuable components, the development and implementation of low-waste technologies.
