Cyanidation and concentration of gold and silver ores. List Gold Refractory Process Methods
The refractory nature of gold ores is often associated with gold finely disseminated in sulphide minerals, such as pyrite, at conventional grind sizes. Conventional milling can liberate the pyrite from the gangue allowing a low mass pyritic concentrate to be produced by a process such as flotation.
Gold in refractory sulfide ores occurs as fine inclusions or in solid solution typically within pyrite, marcasite, and arsenopyrite grains. In this type of ore, because the gold is encapsulated, the interaction with cyanide to form the soluble metal complex is inhibited (Marsden and House, 2006; La Brooy et al., 1994).

Fine grinding also prevents passivation of the leaching mineral by products of the leach reaction. Passivation is normally complete once the precipitated layer is 2 to 3 μm thick. Ultrafine grinding of a mineral to a particle size of 80 passing 10 to 12 μm will prevent passivation as the leaching mineral will disintegrate prior to the
