The ore is treated with dilute sulphuric acid. This trickles slowly through the ore dissolving copper to form copper sulphate. ... There are many types of copper ore found throughout the world. Picture 2 shows the distribution of these deposits. About 80% of all copper extracted comes from sulphide ores.

This invention relates to a method for treating copper ore concentrates, and more particularly to a method ... Several types of copper ore, particularly enargite, contain relatively large quantities of arsenic, e.g., as much as 10-15% by weight and may contain appreciable quantities of antimony, e.g., up to 2% by weight.

Digital Waste Worth More Than Gold, Copper Ore -- article related to Index, Businesses, and Hardware. ... The payoff is huge: computer waste contains 17 times more gold than gold ore, 40 times more copper than copper ore. But the detritus also leaches chemicals and metals into local water supplies."
