4.1.2 Iron Ore Beneficiation Iron ore occurs naturally in a variety of forms, from sand-like iron fines to solid rock masses. Crude ore, or ore mined in the natural state, seldom occurs in a pure state and requires some form of beneficiation. Crude ore is commonly mixed with other minerals (gangue), which reduce the iron content.

For pure magnetite: If oxidation occurs, the magnetic rate of the ore must be lower than 43.0%. In the practice of beneficiation, the following methods are generally used to distinguish between magnetite and non-magnetite: Magnetic Rate> 36%: Magnetite, or unoxidized ore. 28% < Magnetic Rate <= 36%: semi-pseudo hematite, or semi-oxidized ore.
