Typical types of mill used in ore beneficiation are autogenous (AG) and semi-autogenous (SAG) mills together with ball mills to, for example, obtain particle sizes smaller than 100 µm. One process variation that has become increasingly established in recent years is the combination of AG or SAG mill with a ball mill and a downstream agitated ...
