IMPROVEMENT OF PROCESSING OF SULPHIDE COPPER-NICKEL RAW MATERIAL AT THE INTEGRATE WORKS 'PECHENGANIKEL'

There the new classification of ores of Pechenga Deposit has been offered. Most major factors, which determine the opportunity to concentrate the ores, have been ascertained. The mechanism and the kinetics of oxidation of sulphide copper-nickel concentrates in the KS furnaces have been studied. The concentration mode of ores has been improved. The new roasting process of copper-nickel concentrates in the KS furnaces has been developed. The effectiveness of use of schist during the improverishment of converter slags has been showed. The measures to improve the concentration process have been introduced at the Pechenganikel Integrated Works. The data for the feasibility study for the roasting of concentrates in the KS furnaces have been presentedAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
