copper ore extraction by products

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

About 80 of all copper extracted comes from sulphide ores A typical ore contains only 0 5 to 2 0 copper It is a measure of the value of copper that it is worth extracting it from such small concentrations The ore is a mixture of minerals and rock called gangue The most common copper

We shall begin by looking at the mining and processing of the copper bearing ore, followed by an examination of an established and a modern copper smelting process Mining for Copper Bearing Ore There are two categories of copper ore sulphide ore which is processed to enrich it before smelting, and oxide ore that is subjected to acid treatment

Copper is usually found in nature in association with sulfur Pure copper metal is generally produced from a multistage process, beginning with the mining and concentrating of low grade ores containing copper sulfide minerals, and followed by smelting and electrolytic refining to produce a pure copper
