Copper production & environmental impact

• Recycling a tonne of copper uses 20% of the energy that would be used to mine and extract the same copper. • The copper recycling process has much in common as that to extract it, but requires fewer steps. High-purity copper is melted in a furnace and then reduced; Low-purity copper is refined through electroplating in sulfuric acid.

12.3 Primary Copper Smelting

2015-9-10  Mining produces ores with less than 1 percent copper. Concentration is accomplished at the mine sites by crushing, grinding, and flotation purification, resulting in ore with 15 to 35 percent copper. A continuous process called floatation, which uses water, various flotation chemicals, and compressed air, separates the ore into fractions.
