The hydrophobic character of nonsulfide mineral surfaces as influenced by double-bond reactions of adsorbed unsaturated collector species. Progress report, 15 December 1992--14 December 1993
Different collector adsorption phenomena including adsorption density, adsorption state, and conformation have been examined for soluble salt, semi-soluble salt and insoluble oxide mineral systems. In the case of the soluble salt system, the influence of crystal lattice defects on the surface charge of KCl and its flotation response was studied. In the case of semi-soluble salt minerals, the behavior of fatty acid collectors adsorbed at the surfaces of calcite and fluorite was determined by in-situ Fourier transform infrared internal reflection spectroscopy (FT-IR/IRS), multichannel laser Raman spectroscopy (MLRS), and Langmuir-Blodgett (LB) techniques. Finally, changes in the hydrophobic character of the insoluble oxide mineral surfaces of sapphire and quartz were examined with respect to the aggregative nature of the adsorbed collector phase. A number of papers and presentations were prepared from this research and these contributions are listed at the end of this progress report.
