Iron ore Beneficiation There are few basic commodities where the ore can be simply dug up and used without beneficiation. Coal is one and iron ore is another. However, the future for Direct Shipping Ores (DSO) of iron is limited and companies will be forced into processing lower grade ores and using beneficiation to produce shippable concentrates.
