What is the Cost of Mining Gold? Visual Capitalist

May 21, 2013In Nevada, which produces the most gold ounces per square kilometer, about 55% of land is covered. Interestingly, Nevada has produced 225 million oz of gold to date, but the majority of these discoveries have come from outcrop clues on the surface. Imagine what gold could be hidden under soil and gravel within the valleys of the state.

Copper extraction

Copper extraction

Copper extraction. As in all mining operations, the ore must usually be beneficiated (concentrated). The processing techniques depend on the nature of the ore. If the ore is primarily sulfide copper minerals (such as chalcopyrite ), the ore is crushed and ground to liberate the valuable minerals from the waste ('gangue') minerals.
