FIELD: mining.
SUBSTANCE: method consists in crumbling ore, in deslimation, condencing, in contacting pump with soda, depressor and collector on base of tall oil with oxyethylised monoalkykphenols, and in rough, two cleaner and two control flotations. As oxyethylised monoalkykphenols there is used a mixture of α-(isononylphenyl)-ω-hydroxypolyoxy-1.2 ethadyol and product of reaction of one mole of nonylphenol with two moles of ethylene oxide at their weight ratio 1:1. As a collector fatty acids of tall oils are used. The said mixture and fatty acids of tall oil is supplied together into rough and in two control flotation, and as a depressor sulphite-alchohol distillery dreg is used which is supplied into rough and two cleaner floatations.
EFFECT: upgraded efficiency of flotation.
