Iron Mining Process - Minnesota Iron

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. The remaining rock is waste material and is dumped into

Beneficiation of Iron Ores – IspatGuru

The process adopted to upgrade the Fe content of iron ore is known as iron ore beneficiation (IOB). However, Iron ores from different sources have their own peculiar mineralogical characteristics and require the specific beneficiation and metallurgical treatment to get the best product out of it. Also for effective beneficiation treatment, effective crushing, grinding, and screening of the ore is necessary for which suitable crushing, grinding
