Controlling fragmentation
an example metal mine might spend $5.00/t of ore on electricity; an equivalent amount on grinding media in the SAG circuit alone; but only $0.30/t of broken ore on explosives at the drill and blast stage. Yet, the blasting process is a much more energy efficient method of fragmenting rock. The need for energy efficient processing is

Iron Ore Mining Essentials: Key to Steel Production
The first step in the process is the production of pig iron from which the iron ore is converted in the blast furnace and usually occurs in the form of iron oxides. The heated air is blown into the furnace at the bottom which assist in the coking to be burnt and to produce high temperatures (about 1,500°C).
