Реферат: Main aim of this work is a study of model flotation system - xanthate/zinc sulphate by the method of XAFS spectroscopy. All EXAFS and XANES spectra (Zn-K edge) of the samples studied (solution and deposition) were recorded at EXAFS station of Siberian Synchrotron Terahertz Radiation Center (SSTRC). Some changes of local structure of initial solutions of zinc sulfate (having different concentrations from ~10**-4 up to 10**-1 mol/l) between each other and great ones in comparing with bulk samples were found. The presence of different Zn-O forms were detected. For model flotation system - xanthate/zinc sulphate in aqueous solution, the presence of Zn-S forms were found mainly. Structural determination of all interaction forms existing in aqueous solution and deposition were carried out in detail. All possible structural models were discussed. Additionally powder samples of initial reagents and final depositions were characterized by the XRD.
