Copper production begins with the extraction of copper-bearing ores in mining or recycling of scrap metal. The ores are processed into copper concentrate, which can be further treated onsite or sold to a smelter. The figures below represent global production and trade of copper contained within ores and concentrates (ICSG, 2015).

Copper recycling. Recycling copper is far more energy-efficient than mining new copper. It uses only 15% of the energy required to mine and process copper from ore. In fact, nearly 80% of all copper ever mined is still in use today, either in its original form or as part of a recycled product.

Froth flotation is a process used to concentrate copper sulfide ores. Ground ore is mixed with water and reagents, making copper minerals hydrophobic. Air is pumped into the mixture, creating bubbles that cling to the copper minerals and carry them to the surface. The froth, rich in copper, is skimmed off, leaving behind waste material. ...
