Flotation The simplest method of treating a carbonaceous ore is the method described by R. W. Nice (1971) at the McIntyre Porcupine Mine where the carbon, which contains very little gold, is floated off and discarded. The remaining ore is then responsive to cyanidation. This does not work at Carlin because the carbonaceous compounds …

Gold grade measures the amount of gold within ore before it's processed, while gold purity refers to the percentage of gold in the final, refined product. Gold purity is either measured in fineness (the number of parts gold per 1,000 parts) or gold karats, where 24 karat gold is deemed pure.

Zincite is a rare mineral that is insignificant from all but one region in the world. Its bright orange color is very distinctive, as are its mineral association and habits. Pure synthetic Zincite is colorless; its natural orange to red color is caused by impurities of manganese oxide. Zincite often forms together and is admixed with Franklinite.
