Energy use is quite relevant to copper production. Energy consumption has important implications because the process itself requires the combustion of fuels and increasing power requirements that cause greenhouse gas emissions at the thermal power stations that supply electricity to the copper plants (Alvarado et al., 2002).

IN PROCESSING COPPER ORES In recent times, a low copper content in ores has been observed (ores containing 0.2–0.3% copper are used for processing in Canada and the United States, and ores containing at least 0.4% copper are used in Russia [4]) owing to the exhaustion of rich copper resources. The flowsheet of processing copper ores is

Copper ore is extracted from the mine and a first size reduction stage is used to transport the ore for further processing. Pyro-metallurgical and hydrometallurgical processes are used to treat copper ores. As Fig. 2 shows, in the pyro-metallurgy process, copper-sulfide ores are ground to liberate Cu-minerals. After that, it is concentrated by ...

The main raw material is copper sulfide ore, and high-grade copper oxide ore can also be smelted in the pyrometallurgical process. The mining grade of copper sulfide is 0.3–2%, and the average mining grade is approximately 0.81%. The mined ore is crushed and pulverized. Then flotation will separate the copper sulfide concentrate.
