Flotation behaviour of gold during processing of porphyry ...

1997-9-1  Laboratory studie~; on a number of copper-gold ores with pyrite have shown that gold recovery in rougher /scavenger flotation is a function of the pyrite recovered in the concentrate. Figure I shows the relationship between gold and pyrite recoveries in the copper concentrate, using xanthate and dithiophosphate alone, or in combination.

Characterizing gold in refractory sulfide gold ores and ...

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. The liberated gold is readily dissolved in conventional cyanide media ...
