Copper Mining Using Acidothiobacillus microbewiki

In 2009, global copper consumption topped 21 billion tons (Copper Development Association), and that kind of demand has led to the development of sophisticated mining techniques. Copper is rarely found in its native form; most often it exists as ores made up of various copper sulfides and oxides that have little practical value of their own

Copper Mine, Techniques,Ores, Mines, Occurence,

Copper is extracted in large amounts from the Earth's crust by mining of sulphide ores and also oxide ores. The procedure of copper processing involves mining and transporting. Oxide ores are generally processed through hydrometallurgy- heap leaching, solvent extraction and electrowinning. The sulfide ores are usually processed using the method of pyrometallurgy- froth floatation, thickening
