Copper - From Beginning to End. Copper is a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago. And as alloyed in bronze (copper-tin alloy) about 3000 BC, was the first engineering material known to man.
Extraction of copper from ore begins with pre-treatment. Due to the decreasing concentration of copper in ores, this is an important step to decrease the volume of material and to increase the grade of copper in the ore. Most copper ores will only contain a small percentage of copper mineral, with the average grade being below 0.6% copper.

Copper and gold have similar cyanide metallurgy depending on the nature of the minerals present. The processing of gold copper and copper gold ores can be highly problematic, site specific and the process selection is dependent on ore grade, mineralogy, acid leach behaviour, cyanide chemistry, product saleability and environmental considerations.
