Extraction Of Copper Mining, Concentration, Smelting ...
Copper Mining: The commonest ore used in the extraction of copper is Chalcopyrite (CuFeS 2) also known as Copper Pyrites and other such sulphides. The percentage of copper in the actual ore is too low for direct extraction of copper to be viable. The concentration of ore is required and it is done by the Froth Flotation method. Concentration

Copper extraction - Wikipedia
Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.. As in all mining operations, the ore must usually be beneficiated (concentrated).

North America is About to Get Its Largest Copper Mine ...
Aug 13, 2019 Some big copper mines have devastated the surrounding countryside due to acid mine drainage. Ducktown in Tennessee (see above) is a famous site still recovering from copper mining and smelting in the 1900s-60s. The Butte copper pit, once the mine closed, became one of the first Superfund sites thanks to a lake that filled the mine pit with a pH of ~2.5 so acidic it killed birds that
