The Importance of pH in Flotation

In flotation pH control is a vital method to control selective mineral separation A standard depressant that is used is an Alkali An Alkali is any substance that when mixed with Acid will neutralize each other and form a new chemical substance called a BASE This is very important The ore may be either alkaline or Acidic To have a positive control over flotation it is necessary to be

Johnson Matthey Technology Review

In the flotation of platinum group minerals PGMs it has generally been assumed that they will behave similarly to base metal sulfides and thus sulfide reagent regimes are generally used in such flotation plants However the tellurides and arsenides of platinum and palladium contribute about 50 of the PGMs present in the Platreef ore located in the northern limb of the Bushveld Complex of
