FIELD: mining industry. SUBSTANCE: method is applicable, for example, when estimating placer gold in rejects of gold-mining industry. Sample is treated to produce placer complex and slag. Fraction 2 mm is separated from the former and is combined with treatment sludge to form pulp that is subjected to gravity concentration in centrifugal field with intensity 30 to 600 g. Loosening degree of pulp is maintained at the level 0.3-0.5, which is found from mathematical expression. According to invention, pulp in centrifugal field is additionally turbulized. EFFECT: enabled correct determination of gold content in particular test sites and reliable detection of circles with elevated concentrations of metal in examined pits. 6 cl, 2 dwg
