Six steps to process iron ore. 1. Screening ... It is immediately directed to a magnetic separator circuit. Magnetised 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 ...
The principle of the process consists of converting the iron bearing minerals into the magnetic state so that magnetic separation can be employed to concentrate iron from the ore [2]. The gas used for reduction purposes may be either pure hydrogen, carbon monoxide or industrial gases like blast furnace gas, coke oven gas and producer gas.
