When the flotation process is used to treat mineral wastes, there is another important factor that needs to be considered, and that is the quality of the exposed mineral surfaces. Prolonged exposure of the mine wastes to surface processes (e.g. water infiltration) frequently causes mineral surfaces to become corroded (or oxidised).
