The effect of water chemistry on froth stability and surface chemistry

The results of the flotation tests revealed that accumulation of dissolved metal ions and sulfide ions, mainly in the form of SO 4 2− and S 2 O 3 2–, changed both the froth stability and surface chemistry of the sulfide minerals. The froth stability and hence the recovery by entrainment, increased in conjunction with the dissolved ion ...
