Abstract
The authors study the processing behavior of luminophore-containing blends of zinc and cadmium chalcogenides with a view to using them for the modification of the kinetic and spectral characteristics toward enhanced recovery of weakly and abnormally luminescent diamonds usually lost in X-ray luminescence separation. It is shown that zinc and cadmium sulfides activated by copper and silver have the kinetic and spectral characteristics which are the most similar to natural diamonds. The procedure developed for the improvement of the processing behavior of luminophores with zinc and cadmium sulfides includes the circuits of surface activation with copper cations and subsequent treatment in the potassium butyl xanthate solution. The visiometric analysis reveals that the increased oil receptivity of luminophores and the dispersing agents ensure selective attachment of luminophores to diamonds. The bench testing proves feasibility of complete extraction of diamonds to concentrate, including weakly and abnormally luminescent crystals.
