Iron ores with lower iron content such as taconite are first processed to concentrate the iron level and drive off volatile impurities. The iron ore is dressed or crushed into 0.5-1 in. chunks, which increases surface area for reactions. Magnetic separation is used to remove some of the undesirable minerals or gangue in the crushed ore.

The three-stage closed-circuit process is used as a preparation operation for grinding. Whether it is iron ore mined underground or open-pit, as long as the raw ore contains not high mud content, it can work effectively. Therefore, this process is a crushing process widely used in large and medium-sized iron ore concentrators.
