Crushing At the processing plant, the taconite is crushed into very small pieces by rock crushing machines. The crushers keep crushing the rock until it is the size of a marble. The rock is mixed with water and ground in rotating mills until it is as fine as powder. Separation The iron ore is separated from the taconite using magnetism.

Pit-crushing machines pulverize the ore and separate the iron from impurities such as sand and clay. The best grades of ore contain close to 70% iron and usually require less processing. Lower-grade ores may require further refining methods known as beneficiation: Further crushing and washing the ores to remove more sand and clay
