Justification for the Use of Interaction Parameter in Selection of Combination of Flotation Reagents

Composition of collectors is one of the promising avenues in stimulation of flotation efficiency. When using a mix of reagents, their synergetic effect shows up not only at the mineral–liquid interface but at the gas–liquid interface as well. This study aims at connecting the synergetic effect of a cationic / anionic combination collector in reduction of surface tension with synergism of the surfactants in flotation. The tests were carried out to determine surface activity of physisorption in case of combination of these reagents. The results are comparted with the flotation activity and interaction parameter of the components of the combination. The findings can be a framework for the design approach to selecting combinations of collectors for flotation.
