摘要：

The hydrophobic aggregation of fluorite in the presence of Fe3+, Al3+, F- Ca2+, Mg2+ and Ba2+ ions was studied. Electrokinetic potentials were measured to interpret the effect of these ions on aggregation. Dissolved species affected the hydrophobic aggregation either by coating the fluorite surface with hydrolysis products, which reduces collector adsorption, or by inducing a high repulsive force between the particles due to specific adsorption.
