  • 12 Supergene Ore And Gangue Characteristics

    In VMS deposits, copper and other metals are mobilized from primary massive sulfide ore and reprecipitated at depth. This precipitation of Cu sulfides with high CuS ratios can produce an economically significant copper enrichment at the reactive redox boundary between massive sulfide protore and downward penetrating fluids.In VMS deposits, copper and other metals are mobilized from primary massive sulfide ore and reprecipitated at depth. This precipitation of Cu sulfides with high CuS ratios can produce an economically significant copper enrichment at the reactive redox boundary between massive sulfide protore and downward penetrating fluids.Current copper deposits contain significant amounts of secondary non-sulphide minerals and newly discovered deposits are increasingly complex. As a result, research into the improvement of sulphide-oxide copper ores processing through the use of mixed collector systems has surged.CuNiCoAu-bearing massive sulfide deposits associated with maficultramafic rocks of the Main Urals Fault, South Urals Geological structures, ore textural and mineralogical features, comparison

The chemical composition of the ore sample is pre-sented in Table 1. From Table 1, it can be seen that the high copper concentration is in the sample, as well as the high copper oxide content, while the sulfide copper concentration is lower.sulfide-ore copper mines must be fully evaluated to prevent creating major threats to public health. Sulfide-ore copper mining has the potential to release numerous chemicals known to negatively affect human health, including mercury, arsenic, lead, asbestos-like fibers, and air pollution.
