The invention relates to the technical field of wet metallurgy and in particular relates to a method for extracting gold from pyrite. The method for extracting gold from pyrite is characteried in that the pyrite is pretreated so that gold in the pyrite is exposed from the crystal lattices of the pyrite and therefore the gold is capable of certainly reacting with hydrochloric acid and

The final category of gold mining is the processing of Gold ore. This method is largely becoming deprecated as the yield of Gold is often very low and the environmental impact and costs of the operation are substantial. The Gold ore is finely crushed rock or earth containing trace amounts of Gold which are extracted using a chemical process.

The majority of gold ores are classified refractory because the gold mineralogy is contained in sulphides. This type of gold is typically very fine gold or locked in solid solution within sulphide minerals pyrite and arsenopyrite FeAsS. The arsenic bearing pyrite is commonly known as arsenian pyrite and can contain gold in its structure.

The use of oone for the oxidation of cyanidation wastewater has been studied since the 1950s. In the last 2 decades the use of oone to oxidie sulfide ores has been studied. This report presents some of the results obtained concerning the use of oone in the oxidation of raw ores containing gold and silver as well as the treatment of tails or residues of the cyanidation process.
