Mineral beneficiation, particularly base and noble metals, is sensitive to optimum use of reagents, recovery of metals, and clean concentrate. High fluctuation of feed grade at flotation cells yields loss of metals to tailing.

In many lithium ore beneficiation plants, it is a common practice to de-slime the ore prior to flotation. De-sliming is typically carried out to remove the −20 µm size fraction to improve selectivity of separation because slimes are detrimental to the flotation circuit (Bale and May, 1989). As is the case in many operations, de-sliming is ...
