Copper
Pyrometallurgical techniques use heat to separate copper from copper sulfide ore concentrates. Process steps include mining, concentration, roasting, smelting, converting, and finally fire and electrolytic refining. 12.3.2 Process Description2-4 Mining produces ores with less than 1 percent copper. Concentration is accomplished at the

copper ore processing energy used in namibia. Copper Mining and Processing Processing of Copper Ores,Copper processing is a complicated process that begins with mining of the ore less than 1 copper and ends with sheets of 9999 pure copper called cathodes which will ultimately be made into products for everyday most common types of ore copper oxide and copper sulfide undergo two different
Copper processing is a complex process that involves many steps as the manufacturer processes the ore from its raw, mined state into a purified form for use in many industries. Copper is typically extracted from oxide and sulfide ores that contain between 0.5 and 2.0% copper.

In addition, the process can be used to extract copper in situ. That is, without removing the material from the waste pile or from the ground. The net result of the use of this process is that copper can be produced from sources that in the past would have gone untouched, thus reducing the reliance on conventional ore bodies.
Energy costs include electricity and other fuels such as natural gas, fuel oil, coal or coke used in the facilities. Copper smelters are high consumers of energy, although to a much lesser extent than the aluminium ones. Copper refineries are also power intensive processes. The major source of energy in electrolytic zinc smelters is electricity.

Mines are faced with numerous challenges, such as falling raw material prices, declining metal grades in the ores and higher energy prices. Especially because ore processing is particularly energy-intensive, the industry is again focusing on the saving of energy. This report shows what are the key energy saving considerations in the copper and gold mining sectors.

An analysis of energy usage in the production of refined cathode copper was made from mining ore to cathode copper. In mining copper ore the greatest energy consumers are ore hauling and blasting. Another important factor is the “recovery efficiency” of the metallurgical processes used to extract the copper. The mining and mineral concentrating energies are directly proportional to the
