copper ore processing energy used

Copper - Princeton UniversityAll aspects of copper production require energy, whether i n the form of electricity, explosives, or hydrocarbon fuels (diesel, gasoline, natural gas, fuel oil, coal, coke), or as the energy equivalent of materials consumed (e. g., chemicals and steel grinding media). In 1977, the primary copper in- dustry purchased 121 trillion.copper ore processing energy used,Current Energy Requirements in the Copper . - Springer LinkSUMMARY. 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 "re- covery efficiency" of the metallurgical processes used to extract the copper.

Copper extraction - Wikipedia

To improve the process efficiency, lime is used to raise the pH of the water bath, causing the collector to ionize more and to preferentially bond to chalcopyrite (CuFeS2) and avoid the pyrite (FeS2). Iron exists in both primary zone minerals. Copper ores containing chalcopyrite can be concentrated to produce a concentrate.
