Dispersion effect on a lead–zinc sulphide ore flotation
The reagent not only decreases lead grade and recovery in the concentrate, but also increases sharply zinc losses. The activation of sphalerite by dispersants may be explained by the fact that disperse fine galena particles are prone to surface oxidation and, thus releasing Pb 2+ ions in solution. Lead cations are well-known sphalerite activators …
