Hydrophobic character of nonsulfide mineral surfaces as influenced by double-bond reaction of adsorbed unsaturated collector species. Progress report
One of the important collectors in the flotation of nonsulfide minerals is oleic acid. The solution chemistry of oleic acid and its influence on mineral flotation systems have been studied. However, the interaction of such adsorbed unsaturated carboxylates at the nonsulfide mineral surface and its impact on the hydrophobic character of the surface have not been studied. Temperature and oxygen can significantly increase the rate of flotation of nonsulfide minerals. Objective of this research program is to study the interaction of adsorbed unsaturated carboxylates at the surface of nonsulfide mineral systems. Experimental techniques are being used to measure hydrophobic character, adsorption density, surface spectra, and heats of interaction.
