FIELD: mining.
SUBSTANCE: method of detecting rubin-containing calciphyres includes selection of calcite monofractions from alternating zones of calciphyres followed by determining the presence of ruby mineralisation. In selected samples of calcite the luminescence is excitated in the optical wavelength range, and the areas are determined with the presence of ruby mineralisation on a sharp drop in the intensity of radiation in the wavelength range of 600-640 nm.
EFFECT: cost reduction, increased rapidity and reliability of the preliminary assessment of ruby mineralisation.
