When it Comes to Mining, Bigger is Best

Figure 2 Ball mill at Boliden Aitik copper mine. An example of an industry-standard comminution circuit providing high throughputs can be seen in (Fig. 3). This circuit, however, has a high, specific energy consumption per ton of ore processed, driven primarily by the low efficiency of the ball mills and the need to use steel media for grinding.
