Copper Mining and Extraction Sulfide Ores

Ores near the surface can be quarried after removal of the surface layers. The ore is treated with dilute sulfuric acid. This trickles slowly through the ore dissolving copper to form copper sulfate. The copper is recovered by electrolytic refining. Advantages of this process are: See for further information on the leaching process.

The Case for Glycine Heap Leaching

Project Target 2 – Gold ore with nuisance copper. Gold ores with elevated or 'nuisance' copper levels are difficult to process by conventional cyanide heap leaching, as the copper causes high cyanide consumption. As well as the direct cyanide cost, this increases the cost of detoxifying effluent solutions.

From Ore to Finished Product Copper

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 (coppertin alloy) about 3000 BC, was the first engineering material known to man.
