Popis:	The sequence of operations for the processing of secondary raw materials has been proposed based on the analysis of the physicochemical properties of the main metals: copper, zinc, lead and tin contained in the metal concentrate from waste processing, including the developing complete state diagrams of binary systems of copper with lead and zinc, including the melt-vapor phase transition in vacuum. The proposed technology includes preliminary smelting of the concentrate into roughing brass for composition averaging and subsequent distillative extraction of lead and zinc each into roughing metals at a temperature of more than 1000°C with a decrease in pressure from atmospheric to 30 Pa. Copper-base still bottoms can be processed in copper production. Technological studies have confirmed the fundamental possibility of such technological scheme.
