Geology of Copper | Properties, Mining, and Formation of Copper

Copper is found alongside many other types of ore. It can be found near gold, silver, zinc, lead, and other types of metal deposits. When mixed in with other ores, copper is not usually found in great abundance. Until the development of the modern copper mining process, it was typically a byproduct of mining for other metals.

gold cyanidation, silver and copper are commonly present within the solution, which causes their metal ions to react with the cyanide (CN − ), thus forming complexes [1].

Gold-copper ores

The association of gold and copper mineralization in commercially viable ore is a common occurrence. At one end of the spectrum is the predominantly copper ore that contains levels of gold mineralization. This would be uneconomic to mine for its gold content, but the gold provides a significant opportunity value.
