In this work, sulphide copper concentrates of “Almalyk Mining and Metallurgical Combine” JSC were selected as a research material, and the oxidation process at low temperatures with the presence of normal atmospheric air was studied. Low-temperature oxidation is aimed at selective oxidation of iron in the Cu-Fe-S system. The oxidation process was carried out in a Muffle laboratory furnace. In the research work, the oxidation of iron was studied in the temperature range of 100-600 oC. The selective oxidation of iron was studied depending on the degree of separation of the oxidized material into the magnetic fraction.
