In mineral processing, the separation of fine mineral particles after the liberation in post grinding circuit is a recognised challenge. One such problem can be noticed in separating fine particles in an iron-ore slimes beneficiation plant (Umadevi et al., 2013). During classification, it is expected that the denser and/or coarser particle ...
