FIELD: ore dressing.
SUBSTANCE: sodium hydroxide solution, prior to me used for saponification of fatty acids, is additionally agitated for 10-15 min with oxide of a metal exhibiting amphoteric properties taken in amount of 0.1% of the weight of fatty acids and with predetermined volume of water until desired sodium salt is obtained. After that, fatty acid is added and saponification reaction is carried out at stirring for 25-30 min. Ratio of sodium hydroxide, amphoteric metal oxide, and fatty acid under stirring at 40-50оС equals 1.005:0.005:5.
EFFECT: enhanced flotation activity of collector resulting in higher recovery of non-sulfide minerals into concentrate.
