FIELD: process engineering.
SUBSTANCE: invention relates to dressing of minerals and may be used for increasing dressing efficiency. Proposed method comprises grinding to required grain size, and flotation with adding collector and foaming agent T-80. Said grinding is carried out by ore mechanical activation in solution of copper vitriol with subsequent flotation. Note here that said collector represents mix of solutions of potassium isoamyl xanthate per 20 g/t of ore and potassium butyl xanthate per 80 g/t of ore.
EFFECT: higher yield of gold.
