METHOD OF DETERMINING GOLD MINERALISATION OF ROCK FORMATION Russian patent published in 2014 - IPC G01N1/00 B03B7/00 

FIELD: mining.

SUBSTANCE: method of determining gold mineralisation of rock formation comprises multistage crushing of raw material to fractions of the size not greater than 0.5 mm, the subsequent classification of the resulting material and its processing with bromoform. Classification is carried out by sedimentation with the separation of the material class of -0.05+0.02 mm of water discharges, followed by drying and sieving the remaining material with the separation of the fraction -0.5 +0.1 mm and -0.1+0.05 mm, treating each of the resulting classes with 10-30% alcohol solution of bromoform. Sedimentation is carried out once with the accumulation of sediment for 15-20 min and repeatedly for 3-5 minutes, followed by the integration of the water discharges obtained during it.

EFFECT: increase in reliability of determining of gold areas and determining areas of gold mineralisation.
