Surface forces between sphalerite and silica particles in aqueous solutions

Force measurements with the atomic force microscope: Technique, interpretation and applications

“…Muster et al [616] studied the interaction between zinc sulfide particles under conditions typical for the refinement of zinc ores. Surface forces between a fractured sphalerite surface and a silica particle at different pH and ionic conditions were found to correlate with sphaleritesilica heterocoagulation tests [617]. Fa et al [618] prepared spherical particles of calcium dioleate which is used as collector colloid in flotation of calcites and fluorites.…”

QCM-D study of nanoparticle interactions

“…Although zeta potential distribution, particle size distribution, settling rate, and direct colloidal force measurements can be used to study the homo-and heteroaggregation of zinc sulphide and silicate minerals, [188][189][190][191][192][193][194][195]…”

The Colloidal Probe Technique and its Application to Adhesion Force Measurements

“…Consequently, a strong adhesion occurred under these conditions that could be further increased by addition of copper(II) ions. To better understand contamination of the sphalerite (ZnS) concentrate by silica in mineral flotation, Xu et al [91] measured the adhesion between a fractured sphalerite surface and a silica particle ($ 4 mm radius) in electrolyte solutions. At low pH values in KCl solutions, a pronounced adhesion of up to 18 mN/m was observed.…”
