Developments in fine and ultrafine grinding technologies for the minerals industry

Significant reduction in liberation size of mineral deposits in worldwide has challenged the minerals industry to come up with efficient technologies to reduce the enormous energy required for fine and ultra fine grinding and to achieve economically the required recovery and grade for targeted minerals. Mingwei Gao and Ralph Holmes of CSIRO Minerals, Australia discuss the various mill types including the Tower Mill and IsaMill.
