· 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 ).

· Use of NaHS and silver ions has been reported to improve gold recovery at the Los Pelambres mine in Chile (Chryssoulis 2001 ). Sulfide ions appear to act as flotation activators at low concentrations less than 10 −5 M, whereas at concentration above 10 −5 M, it acts as a depressant (Aksoy and Yarar 1989 ).

Beneficiation is the technical term describing the industrial process of mechanically separating minerals from each other. No chemical changes to the minerals are made at this point in the mining process. The phosphate ore, or “matrix” as it is called locally, contains three different mineral groups which have to be separated from each other.
