Mine tailings, the byproduct of mining and mineral processing, are increasingly mass produced as a result of increased demand for metals and minerals as well as the advancement in technology that allows for the exploitation of lowergrade ores. Lower grades can increase the volume of tailings that may contain new gangue minerals that should be evaluated for the presence of critical minerals ...

The latter comprises 100m³ of rougher cells, a regrinding mill, and Jameson cell cleaner and scavenger flotation. During 200102, the concentrator capacity was expanded by 30% to maintain metalinconcentrate output at 190,000t/y of copper and 600,000oz/y of gold. A pebble crushing circuit and additional grinding capacity were installed.

HS: Traditional horizontal mills are generally not particularly energy efficient. Only a very small part of the energy is transformed into efficient grinding, with the remaining energy channeled into liner and media wear, heat and noise. In terms of technology, there is not much that can be done with the mill itself except for the engine and ...

Ball mills as well as rod mills are widely used in the mining industry on account of their simplicity. Ball mills in particular play an important role in secondary grinding of ores to final particle sizes smaller than 100 µm. The market leader Outotec alone has delivered more than 8000 such mills for the mining industry (Fig. 11).
