Mining industry requires high amounts of energy to extract and process resources, including a variety of concentration and refining processes. Using energy consumption information, different sustainability issues can be addressed, such as the relationship with ore grade over the years, energy variations in electricity or fossil fuel use. A rigorous analysis and understanding of the energy
Treatments costs are those of the smelting process which uses heat to melt metal in order to extract it mechanically from the ore. Refining costs are those of electro-refining processes, the output of which is metal that is pure enough to be sold for most purposes. Treatment and refining costs are an important component of the cash cost of mining.
