Minerals With Carbonaceous Gangue

These minerals contain the carbonous minerals under an organic or mineral form. This carbon can re-precipitate the dissolved gold which gets lost then between the residues.

The treatment of such a mineral needs in an upward movement of the Cyanidation one stage of oxidation of the mineral, one separation by flotation of the carbon or the adding of reactive, like the kerosene, re-covering the surface of the carbon minerals

Gold Minerals Which Are Associated with Ground Minerals
These types of mineral assure a great part of the world production. The gold is habitually recuperated with the concentrates of sulphurs of the metals of base, copper, lead or zinc.

The sterile parts of the flotation, when they still contain the gold, can be cyanidated.
