Copper Mining and Processing Processing Copper Ores

Copper Production in Zambia in Five Easy Steps. How it is

Sulphide oretreatment process. The copper is liberated from the sulphide ore through a chemical processes called flotation. The resulting copper mixture is called concentrate which is a grey-black powder that looks a bit like ash. It is roughly 30 copper and may also contain traces of gold and silver.

Copper Mining and Extraction Sulfide Ores

Mining copper About 200 years ago the UK was an important world source of copper and tin and there were mines in Cornwall and Devon. These mines have now closed and today the biggest copper mines are in Chile (Escondida mine) and Indonesia (Grasberg mine). These produce many millions of tonnes of copper ore per year.
