This work constitutes a fundamental study of the interaction between soluble sulphide,copper (II) oxide and cerussite particles in the presence of Ca²⁺ ,Mg²⁺ starch , gum arabic and Triton X- IOO . A detailed investigation of the effect of pH of the system on the rate of sulphide uptake was made . In addition , the structural form of the surface precipitat.es were determined with the aid of scanning electron microscopy . On the basis of these results , it was concluded that adsorption of sulphide on cerussite in the presence or absence of Ca²⁺ starch, gum arabic and Triton X-IOO could either lead to the formation of a non-uniform or a uniform sulphide layer depending on the experimental conditions . However , the interaction of copper (II) · oxide wi th soluble sulphide in the presence or absence of the above mentioned species always led to the formation or a non-uniform sulphide layer . Preliminary experiments of the interaction between xanthate and sulphidized surface showed that oxide surface covered with metal sulphide layer reacts with less xanthate than the free oxide surface.

The chemistry during regrinding is critical to flotation. It has significant effects on mineral surface properties and can lead to different mineral floatabilities. This research seeks to quantify contributing factors to changes in mineral flotation behavior with grinding and regrinding. The influence of the particle breakage mechanism on mineral floatability is also investigated. In this research, sulphide mineral surface species and hydrophobicity were analyzed by a range of techniques, including X-ray photoelectron spectroscopy (XPS), surface area measurement (BET), ethylene diamine-tetra acid (EDTA) extraction and contact angle measurements. / Thesis (PhD)--University of South Australia, 2010
