Copper Mining and Extraction: Sulfide Ores

This is not enough to make it commercially viable to extract the rock. Copper mines are only set up where there is more than 5 kg of copper per tonne of rock (0.5% by mass). Ideally, the figure should be closer to 2%. The world's largest copper ore deposits are found in Chile on the west coast of South America.

Gold is usually found alone or alloyed with mercury or silver, but can also be found in ores such as calaverite, sylvanite, nagyagite, petzite and krennerite. Most gold ore now comes from either open pit or underground mines. The ores sometimes contain as little as ...
