INTERACTION OF IRON-SILICATE MELT WITH GAS MIXTURES CONTAINING SULFUR AND METHANE DIOXIDE

摘要

Together with the Institute Gipronikel', Noril'sk Kombinat has attempted to develop a new ecologically clean technology for the depletion of slag rich in nickel, copper, and cobalt. The critical element in the technology involves scavenging of the slag melt using a reduced sulfidizing gas mixture. A sulfide phase (matte) and slag which is deficient in non-ferrous metals is formed as a result of the interaction.
