Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different ...
The early development of copper probably was most advanced in Egypt.As early as 5000 bce, copper weapons and implements were left in graves for the use of the dead.Definite records have been found of the working of copper mines on the Sinai Peninsula about 3800 bce, and the discovery of crucibles at these mines indicates that the art of extracting the metal included some refining.
Canada is the fifth-largest mine producer of copper in the world. Most of the copper concentrate from mines in eastern Canada is converted to copper metal (99% pure) at smelters located at Flin Flon, Man, Sudbury and Timmins, Ont, and Rouyn-Noranda and Murdochville, Qué. Canadian smelters also process imported copper concentrates and a variety ...
Copper mining waste storage piles may be as large as 1,000 acres and typically include three types of waste; tailings, dump and heap leach wastes, and waste rock and overburden. The amount of marketable copper produced is small compared to the original material mined.

Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef or placer deposit.These deposits form a mineralized package that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay.
