Copper Mining and Production Processes Explained

Leaching offers an alternative to copper mining. First, the ore is treated with dilute sulphuric acid. This trickles slowly down through the ore, over a period of months, dissolving copper to form a weak solution of copper sulphate. The copper is then recovered by electrolysis. This process is known as SX-EW solvent extractionelectrowinning.

Innovations in Copper Mining amp Extraction Producing

The Gall-Copper Process was recorded as being used during the Song Dynasty 960-1271AD. Copper was precipitated from solution by dipping iron into the blue vitriol solution - a process identified as early as 150 BC in China. 6 Therefore, presumably, the recognition of a natural copper leaching process can be identified as early as that date.
