Copper mining From ore to copper

What's in an ore? There are many types of copper ore found throughout the world Picture 4 shows the distribution of these deposits About 80% of all copper extracted comes from sulphide ores A typical ore contains only 0 5% to 2 0% copper It is a measure of the value of copper that it is worth extracting it from such small concentrations
