Abstract
Electroacoustic measurements (AcoustoSizer, Matec Applied Sciences) of zeta potential and particle size-distribution are reported on well ch aracterised ultrafine (-5 mu m) sphalerite and galena particles. For b oth sulfide minerals the zeta potentials determined electroacousticall y are in good agreement with those determined using the more conventio nal microelectrophoresis. The applicability of the electroacoustic tec hnique to sulfide mineral particles is discussed in particular the inf luence of interparticle interactions, surface oxidation, pH and partic le solids concentration.
