The use of solar energy in the copper mining processes
For copper ores, the processing accounts for 45% of the total energy requirements, extraction, and material handling 45%, and general and administrative costs (10%) (Curry et al., 2014). Energy in the copper mining industry is needed in three forms namely: electricity, heat, and fuel.
The Extraction of Copper
Sulfide ores such as chalcopyrite ((CuFeS_2)) are converted to copper by a different method from silicate, carbonate or sulfate ores. Chalcopyrite (also known as copper pyrites) and similar sulfide ores are the commonest ores of copper. The ores typically contain low percentages of copper and have to be concentrated before refining …
