In present-day practice, the ore is reduced to a size many times finer than can be obtained with crushers. Over a period of many years, various fine grinding mills have been developed and used, but the ball mill has become standard due to its simplicity and low operating cost. A ball mill efficiently operated performs a wide variety of services.

Ferrous metals need to be extracted from basic iron ore. The original source for iron ore is the earth's crust, which bears metals and metal compounds such as iron oxide. However, the ore is commonly mingled with other materials. For the purpose of optimizing the usage of the metal, it has to be derived from the mixture.

Most new steel mills were located near the southern end of Lake Michigan- Gary in Indiana, Chicago, and other communities. The main raw materials continued to be iron ore and coal, but changes in steelmaking required more iron ore in proportion to coal. Thus, new steel mills were built closer to the Mesabi Range to minimize transportation cost.

Integrated coal-fueled steel mills accounted for ∼60% of the 1.4 Gt of global steel produced in 2008, consuming 15–18 GJ per t-steel produced and emitting a global average of ∼1.4 t-CO 2 per t-steel produced. In the first stage of the steelmaking process, high-grade coal (anthracite) is used to fuel a blast furnace in which iron is extracted by reduction from the ore hematite (Fe 2 O 3 ...

This raises some very interesting questions about the economics of China's large-scale use of domestic low-grade iron ores with an Fe content as low as 25%. Australian iron ore exports come overwhelmingly from Western Australia, and the breakneck increase in production over the past decade has gone wholly to feed the iron mills of China.
