The main aim of selective comminution is the separation of the valuable content from waste material, thereby relieving the subsequent beneficiation process. The different comminution behaviour of ore constituents is exploited to generate a product, which shows an enrichment of the valuable content in certain fractions.

Significance of Mineral Beneficiation 2.
Mineral flotation is by no means the only way of achieving effective separation. Gravity separation, also known as gravity concentration, is based on the differential movement of mineral particles in a viscous fluid (e.g. water) due to their differences in specific gravity and one or more other forces (e.g. resistance to motion; Wills and Finch ...

Following the comminution, a single stage of either gravity separation in a Reflux Classifier or single stage of magnetic separation in combination with a Reflux Classifier could be used to deliver the final concentrate. There would be no need for the initial desliming stage, which usually involves hundreds of cyclones, and there would be no ...
