Copper ingots receive from the corresponding ore or cupriferous waste of nonferrous metallurgy. The main way of receiving production – pyrometallurgical. After enrichment raw materials are exposed to melting in flame reflective furnaces at a temperature of 1450 °C. Matte – an alloy from 20 … 50% of copper and 20 … 40% of iron is as a result formed, containing also 22 … 25% are gray, about 8% of oxygen and various impurity (compound of nickel, lead, zinc). Then matte blow compressed air in horizontal converters at a temperature of 1200 … 1300 °C, emitting from it draft copper (concentration of an element - 98,4 … 99,4%) which then is spilled in ingots or other forms. Then production is exposed to refinement to the necessary concentration of a basic element (content of copper of 99,95% corresponds to the M0 brand, 99,9% - the M1 brand, etc.)
