    In Pergamon Materials Series, 1998. 10.6.6.1 Matte-slag-gas reactions in Cu-Fe-Ni sulphide ores. Sulphide ores are a major source of Cu, Ni and precious metals. A basic principle of the extraction processes is to blow air into the molten sulphide in order to oxidise (1) S, which forms a gas and (2) Fe, which forms predominantly FeO and then partitions to a slag phase which covers the matte.

  • Mineral processing

    Dewatering is an important process in mineral processing. The purpose of dewatering is to remove water absorbed by the particles which increases the pulp density. This is done for a number of reasons, specifically, to enable ore handling and concentrates to be transported easily, allow further processing to occur and to dispose of the gangue.

  • Flocculation in Mineral Processing | SpringerLink

    Abstract. Flocculation is a characteristic property of colloidal dispersions. The typical classical sol contained sub-microscopic dispersed particles which would pass freely through ordinary filter-paper, and were too small to be resolved by any transmission optical microscope. Consequently, an arbitrary size limit of 0.1 μm could be defined as the upper size boundary of the colloidal range.
