Mining and Mineral Use Earth Science

Mining and Mineral Use Earth Science

Copper is mined and extracted from copper ores. To extract the metal from the ore, the rock is melted at a temperature greater than 900 C, which requires a lot of energy. Extracting metal from rock is so energy intensive that if you recycle just 40 aluminum cans, you will save the energy equivalent of one gallon of gasoline.

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.
