| Abstract: | The activation and deactivation of sphalerite flotation were reviewed. The sources of ions which could activate sphalerite flotation were discussed. The mechanism of activation is affected by pH value, the potential of slurry, concentration of the activator and lattice imperfection. Sphalerite and marmatite are effectively activated by ammoniacal copper complex ion, which can lower the cost and improve the quality of zinc concentrate. The deactivation will be generated by removing the activate ions or hydrophilic film coating on sphalerite surface. And the research directions of theory and technologies of flotation for polymetallic sulphide ores based on the use of recycled water, inside and outside environmental of minerals and new flotation agents were also predicted.Key words: sphalerite; flotation; activation; deactivation; unavoidable ions |
