The Process In Which Iron Ore Is Separated

The Six Main Steps of Iron Ore Processing Multotec Canada

Magnetized drums collect magnetic material, so it can be further concentrated (magnetite iron minerals content). The lighter particles that were separated during the spiral gravity separation step are rolled into balls (combined with bentonite or a similar binding agent) and cooked in an induction oven. This process is known as pelletization.
