Rcovery of gold in pyritic ores - Mine Engineer.Com

The gold flakes are very small in size, 5-10 microns. The pyrite in which small amounts of gold occurs is of crystalline variety (primary pyrite). The characteristics of primary pyrite are a absence of porosity, an extreme brittleness, a resistance to oxidation, and the existence of gold possessing a weak susceptibility to magnetism (due to a fine coating of a iron compound).

Gold Ore

Gold Ore has found a way to harness this powerful energy and use it for something good. Chemical reactions are governed by the interaction of energy and matter. Imploding cavitating bubbles generate temperatures of up to 5,500°C and pressures of around 1,000 atmospheres, creating a highly reactive environment for mass transfer and chemical reaction.

The slurry that remains after this process has a very fine particle size. Typically, 80% of the ore particles are less than 70 microns in size (about the same consistency as fine beach sand). Such a fine particle size is required for gold liberation – the size required for the cyanide to be able to ‘see’ the gold in the leaching process.

Liberation: Cyanide leaching will only be effective if the cyanide can come in contact with the gold particle. For this to happen, the ore should either be sufficiently porous for cyanide to reach the gold, or more usually the ore is crushed and ground to a size at which the surface of the gold is exposed – i.e. the gold is liberated.
