Rcovery of gold in pyritic oresMine Engineer.Com
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.

Sulphide Gold Ore Treatment by Leaching and Flotation Process
There are many arrangements and combinations using flotation in conjunction with treatment of gold ores. The two gold process flowsheets shown, with some variations, are probably the most commonly used.. In Gold Flowsheet No. 1 the ore is ground in water to such a size as to free the minerals sufficiently to produce a tailing by flotation low enough in value that it may be discarded.
