Processing Copper Sulphide Concentrates

A method of processing sulphide copper- and/or sulphide copper-zinc concentrates comprises flash smelting of said concentrates and basic silicate fluxes in the presence of oxygen with the resultant formation of a dispersed mixture of highly basic molten slag containing copper and zinc oxides, metallic copper and white matte. The initial concentrates and silicate fluxes are taken in ratios ...

hydrometallurgical process for processing copper sulphide concentrates to metal. The basic concept of this process is to allow processing of concentrates on site at the mine, to minimize downstream costs, including freight on concentrate. Although it has outstanding environmental features, the CESL Process also has to be

By way of example, a copper concentrate could include chalcopyrite (CuFeS2), containing 34.6% copper, possibly another sulphide such as pyrite (FeS2) and other waste (or gangue) minerals. The overall grade of the concentrate could be in the range 22% to 30% copper. Concentrates are usually specific to particular smelters.
