Copper Mining and Production Processes Explained

An ore is a rock containing enough valuable mineral to make it worth extracting In the case of copper it is worth extracting when there is about 2 kg of copper per 1 000 kg of ore Copper minerals are found in over one hundred varieties although only a few have been worked for copper on a large scale.
