FIELD: metallurgy.
SUBSTANCE: method involves separation of Bessemer matte into metallised and sulphide fractions and oxidation leaching of metallised fraction with solution at the controlled chlorine supply. At that, ratio of sulphur and copper contained in metallised fraction is 0.3-0.7. Leaching is performed in the value range of oxidation-reduction potential of 430-470 mV, preferably 440-450 mV. Sludge of baths of electrolytic nickel refining of processing technology of sulphide Bessemer matte fraction is supplied together with metal faction of Bessemer matte for leaching.
EFFECT: reduction of flow of reagents and scope of equipment, simplification of instrumentation of the process, reduction of losses of precious and non-ferrous metals and improvement of incomplete production.
