How is iron ore removed from the open pit mine?
How is iron ore harvested? 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. The iron ore is separated from the taconite using magnetism
