It has been estimated that grinding consumes up to 4% of global electrical energy and accounts for more than 50% of the total energy used in mining operations. In addition, more than 90% of the total energy supplied in beneficiation plants is dissipated as heat, kinetic energy, noise, and inefficient breakage of ores/raw material.

grinding media were the result of increased corrosion between this media type and the sulphide minerals in the ore. It was postulated that the improvement in fine (–3 micron) galena flotation response when the ore was ground with high chrome grinding media was due to lower levels of oxidized iron species within that system.
