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.

Waste arising from mining is called gangue. Both surface and underground mining often require large quantities of rock to be broken away to reach the ore. Gangue is usually placed in heaps near the mine. Many Swedish mines use parts of the gangue as a resource, e.g. as aggregate for road construction or to refill mined rock chambers and open pits.
