Energy Consumption in Mining Comminution
In the mined material supply chain, ore concentration is the process whereby the mineral being mined is separated from mineral bearing rock, either chemically or physically. Prior to this the ore must be crushed to a size suitable for grinding. Grinding is then done to produce fine particles which can be processed either chemically or physically.
