Gold mine's mining operation represents the stage during which ore is extracted and processed into gold, which can take between 10-30 years. In order to process gold, rock and ore must be transformed into a metallic alloy with a substantial gold content - called doré - typically in the range of 60-90% of gold.

Pyrrhotite floats best in acid circuits. The pH range for flotation for gold sulfide ores containing pyrite and arsenopyrite is generally between 7 and 9. Flotation may be carried out at higher pH values of 9–10, since this favors the depression of talc minerals and avoids the use of expensive gangue depressants.

In one, the ground ore is put into a tank containing a weak cyanide solution and zinc is added. The zinc causes a chemical reaction which separates the gold from the ore. The gold is then removed from the solution with a filter press. For the carbon-in-pulp method, the ground ore is mixed with water before cyanide is added.

If no gold or native silver can be seen in the rock, take a representative sample of about 300 grams and grind it up to pass a No. 30 sieve. Weigh out 250 grams and carefully pan down until most of the gangue is removed. Examine the heavy residuum for metallics. Should any be found it will be well to see how much can be amalgamated.
