The ore crushing process includes four types: ore coarse crushing, ore medium crushing, ore fine crushing, and ore superfine crushing. Ore coarse crushing is a process of crushing ore blocks with a feeding particle size of 500–1500 mm to 125–400 mm. The maximum crushing ratio of coarse crushing is about three.

Major Mines & Projects | Rossing Mine
After weighing, the fine ore is stored. Coarse ore is withdrawn from the stockpile by vibrating pan feeders, feeding directly onto a coarse ore reclaim conveyor. This conveyor discharges the ore to a pre-screening plant where all fines are removed and the coarse material returned to the surge bin ahead of the secondary crushers.
