FIELD: mining.
SUBSTANCE: invention concerns mineral dressing, particularly flotation dressing methods, and can be applied in processing diamond-bearing ores. The method of diamond-bearing ore flotation involves non-polar black oil based collector, heteropolar collector, and foaming agent. Non-polar black-oil based collector is a black oil fraction obtained in the process of direct oil refining at 280°C and processed previously with MPK-3 depressor additive at the following component ratio: black oil fraction 99.6%, MPK-3 depressor additive 0.4%.
EFFECT: increased rate of diamond extraction to concentrate; improved process selectivity.
