Mining Method For Chalcopyrite

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 ...

Leaching Chalcopyrite is the holy grail for hydrometallurgists (Leachers), difficult to leach as the sulfur forms a layer over the mineral and makes the leaching slow. Having said that, it is not not leachable, not unusual for ore dumps (low grade) containing chalcopyrite to be placed under leach but report low recovery +/-30% TCu over several years and the rate is around 0.5-1% per month.

Copper Mining: The commonest ore used in the extraction of copper is Chalcopyrite (CuFeS 2) also known as Copper Pyrites and other such sulfides. 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.
