  • Mining and Mineral Use

    Copper is mined and extracted from copper ores. To extract the metal from the ore, the rock is melted at a temperature greater than 900C, 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.
