18-11-2015· Copper extraction techniques refers to the methods for obtaining copper from its ores. The method used to extract copper from its ores depends on the nature of the ore.
Processes: copper mining and production. Copper is found in natural ore deposits around the world. This page explains copper mining: the production route taken from ore-containing rock to a final product that is the highest-purity commercial metal in existence and used in a wide variety of applications essential to modern living.

About 200 years ago the UK was an important world source of copper and tin and there were mines in Cornwall and Devon. These mines have now closed and today the biggest copper mines are in Chile (Escondida mine) and Indonesia (Grasberg mine). These produce many millions of tonnes of copper ore per year. The main ores of copper are sulfides and
Extraction Ores are first mechanically crushed and ground so that nearly all copper mineral particles are freed from the gangue. Flotation by the injection of air and violent agitation is carried out with the pulverized ore held in suspension in water, to which surface-active agents have been added.
Telfer oxide ore, which was not found to be preg-robbing, enhanced gold extraction was observed at low cyanide concentrations, but not at high concentrations, as the gold was completely extracted by cyanide alone.
