International Journal of Engineering and Information Systems (IJEAIS)   Year: 2021 | Volume: 5 | Issue: 5 | Page No.: 7-14 The Current State of Copper Metallurgy and Its Raw Material Base Shokhrukh Toshpo'latovich Khojiev, Mohichehra Saburovna Ergasheva, Shamshod Farkhod o'g'li Khamroqulov, Javokhir O'tkir o'g'li Khamroev Abstract: Sources of copper production are ores, their enrichment products - concentrates - and secondary raw materials. The share of secondary raw materials currently accounts for about 40% of the total copper output. Copper ores are almost entirely polymetallic. Possible natural companions of copper, like other heavy non-ferrous metals, are the elements of the 4th-6th long periods of the Mendeleev's periodic system. Valuable companions of copper in ore raw materials in various combinations can be about 30 elements. The most important of them: zinc, lead, selenium, tellurium, cadmium, nickel, cobalt, gold, silver, sulfur, germanium, rhenium, thallium, indium, molybdenum, iron. In cases where copper-bearing ores contain significant amounts of other satellite metals, commensurate with the copper content, they are called copper-nickel, copper-zinc, copper-lead-zinc, etc. All types of ores are used in copper production: sulfide (solid and disseminated), oxidized, mixed and native. However, the main copper raw material is sulfide phenocrysts, the reserves of which in the subsoil are the largest. 85 - 90% of all primary copper is currently obtained from sulfide ores.
