Why are the sulfide ores generally converted to an oxide and then

Sulfide ore is roasted before reduction it is because A metal oxide is usually less stable than metal sulfide Therefore the reduction of metal oxide is easier as compared to the reduction of metal sulfide Hence a sulfide ore is first converted into its oxide before reduction in the presence of an excess of air

Silver MIning Solution Mineral Processing

Sulfide ore can be floated from the ore as concentrate and then the gold and silver in the exposed sulfide can be roasted and then cyanidated Because the gold and silver in the middle and tailings after flotation are still high they need to be cyanidated for recovery 5 Cyanide flotation

Gold Oxide AMERICAN ELEMENTS

Gold Oxide is a highly insoluble thermally stable Gold source suitable for glass optic and ceramic applications Gold oxide is a red brown solid that is the most stable oxide of gold but decomposes at 160 ° Oxide compounds are not conductive to electricity However certain perovskite structured oxides are electronically conductive finding

Characterizing gold in refractory sulfide gold ores and residues

Abstract Gold is present in refractory sulfide gold ores mainly in arsenian pyrite and arsenopyrite where it occurs in both the chemically bonded state and as nano size grains of metallic gold During roasting or pressure oxidation the sulfide matrix is destroyed and essentially all the gold is converted to the metallic form
