Abstract

AbstractThe integrated thermodynamic calculations and spectral analyses validated concentrations of hydrophobization agents (butyl xanthate and sodium oleate) to ensure chemisorption and chemical interaction with silicate matrix of luminophore FL-530. It is found that in the optimized conditions, hydrophobization agents interact with zinc orthosilicate without volume reaction which degrades spectral characteristics of luminophore. The increased oil receptivity of luminophore FL-530 improves its ability to remain in the organic phase of emulsion and to better attach to the surface of diamonds. The UV visiometrics revealed better attachment of hydrophobic luminophore at diamonds. The optimal concentrations of solutions of butyl xanthate and sodium oleate are determined. The tests using separator Polyus-M proved efficiency of hydrophobic luminophore FL-530 which essentially enlarged amplitudes of the fast and slow signal components in X-ray fluorescence of slight fluorescent diamond and their recovery in separation.
