Improvement of Concentration Technology of Cu-Ni Ores Processed at Concentration Mills of MMC Norilsk Nickel

摘要

One of the most efficient trends of improving mining and metallurgical production at MMC Norilsk Nickel is modernization of the technological process of concentration ensuring production of high-quality concentrates, which leads to a substantial cost saving at subsequent metallurgical process stages. The task of copper-nickel production at Kola MMC consisted in increasing Ni (?_(Ni)) content in the concentrate from 8 to 12-15%, reducing the mass fraction of MgO from 11-14 to 5-6%.
