The ore needs to be crushed, as a choc chip biscuit, to get the minerals out. Once we have crumbled the choc chip biscuit, the chocolate pieces can be separated from the crumbs. In the same way in the mining process the valuable minerals can be separated from the unwanted rock. The unwanted rock is called waste rock
Crushing is an important step in the complex process of mineral processing (Fig. 1). In open pit mines, rock chunks with edge lengths of 2 m have to be processed. In underground mines, the biggest chunk sizes are about 0.5 m. Crushers have the task of reducing the ore rock to particle sizes in the millimetre range for subsequent grinding
