Copper Mining and Extraction Sulfide Ores

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. This is due to the volcanic activity that is part of the process that created the Andes mountain chain.
