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.

The majority of world crude steel is made from the BF-BOF route. Ores carrying very high quantities of hematite (greater than ∼60% iron) are known as "natural ore" or DSO, meaning they can be fed directly into the BF-BOF route. However, low-grade ores need to be beneficiated before they can be used to make steel.
