Magnetite ore known as Run-of-Mine (ROM) material is direct dumped by haul trucks from the mine into the primary crusher. Primary and secondary crushers crush the ROM ore to a product size of <60 mm. The crushed ore is then transferred to the Coarse Ore Stockpile (COS), which has a holding capacity of up to 500,000 tonnes of material for downstream processing.
