Copper extraction refers to the methods used to obtain copper from its ores. If the ore is primarily sulfide copper minerals (such as chalcopyrite)the ore is crushed and ground to liberate the valuable minerals from the waste (gangue) minerals.
Copper orein concentrations ranging from 0.29 percent to ten times that amountis mined from open pit or underground mines. The crushed mine ore is ground in rod and ball mills and then sent to flotation machines where the copper mineral rises to the top in a frothmaking a copper concentrate of approximately 30 percent27 percent iron and 33 percent sulfur.
Why Is Copper Ore Crushed. The copper ore is crushed and ground to a size such that an acceptably high degree of liberation has occurred between the copper sulfide ore minerals and the gangue minerals. The ore is then wettedsuspended in a slurryand mixed with xanthates or other reagentswhich render the .

Jun 052020 Copper stamp mines crushed the copper out of the surrounding rock and produced massive amounts of sandor tailings. Iron waste was less toxic than copper tailingsbut the refining process added significant quantities of mercury to the watershed, environmental historian Nancy Langston wrote in Sustaining Lake Superior: An
Copper is extracted in large amounts from the Earths crust by mining of sulphide ores and also oxide ores. Studies reveal about 80% of copper is produced by its extraction from sulphide ores. Chalcopyrite is a certain kind of suphide ore that can be converted to copper by a different method from silicatecarbonate or sulphate ores.

In the ore-dressing plantthe material received from the mine is crushed in several stages and finely ground to a size which ensures that copper minerals are liberated from the waste materialsor gangue. In cases where the next step is leaching (most frequently in the case of oxide ores)complete liberation of the copper minerals is not
Open-pit: 90% of ore is mined using the open pit method. Ores near the surface can be quarried after removal of the surface layers.
