  • Roasting (metallurgy)

    Sulfating roasting Sulfating roasting oxidizes certain sulfide ores to sulfates in a controlled supply of air to enable leaching of the sulfate for further processing The sulfide ores of copper are heated in the reverberatory furnace If ore contain iron it is mixed with silica before heating.

  • A technique to determine ore variability in a sulphide ore

    There are a number of studies with sulphide ores and/or sulphide minerals showing effects of surface oxidation on flotation performance While low degree of surface oxidation may enhance flotation ( Buckley and Walker 1988 Trahar 1984 Luttrell and Yoon 1984 ) excessive surface oxidation generally diminishes flotation recovery and selectivity ( Senior and Trahar 1991 Smart 1991 ).
