FIELD: process engineering.
SUBSTANCE: invention relates to mineral dressing and may be used in processing hard-dressing slime gold-bearing ores and placers. Proposed method comprises preparation of material, additional of sorbent and hydrophobisation in flotation. Pulp preparation is effected by sizing the material to under 0.005 mm with water addition at pulp-to-water ratio of 1:5. Note here that flotation processing is performed with adding minced sorbent being mixed at the following ratio of components: butadiene rubber - 20-60, carbon - 80-40. Note also that butyl potassium xanthate and foaming agent T-80 are added after addition of minced sorbent.
EFFECT: higher yield.
