Copper Mining and Production Processes Explained

Copper ores. 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 0.2 . Copper minerals are found in over one hundred varieties, although only a few have been worked for copper on a large scale.
