Abstract
The authors have correlated the fluorescence spectrum with the spectrum and kinetics of X-ray luminescence of organic collectors. The correlations prove applicability of organic collectors with modifying agents. From the integrated evaluation of organic liquids by the criteria of their adhesion capacity relative to diamonds and extraction capacity relative to inorganic luminophores, the selected organic collectors are: diesel, heavy gasoil of catalytic cracking, and their mixture. The spectral functions of organic luminophores contained in organic collectors are replaceable with polyaromatic hydrocarbons which generate intense signals similar to the signals of organic luminophores. Efficiency of modifying agents containing organic collectors and hydrophobic luminophores E-515-115-G5 and FL-530-GZ is high. The test organic collector was heavy gasoil of catalytic cracking and diesel fraction at a ratio of 61–9:1. Recovery of weakly and abnormally fluorescent diamonds was 80–90%, while recovery of kimberlite was not higher than 1%. The results allow recommending the developed modifying agents for the commercial-scale X-ray luminescence separation of diamond-bearing materials.
