Water and Energy Use in Mineral Processing: A Case Study in Copper
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).
