FIELD: concentration of minerals, mainly, diamond-containing ores with oil show. SUBSTANCE: method includes wet grinding of ore, desliming of mill outflow with separation of dump waste product, size classification of mineral concentration of fine fractions of material by gravity method and separation of dump waste product, foam separation of gravity concentrate with production of dump tailings and finished product after concentrate finishing. Prior to grinding, ore is held under natural conditions for 4-6 months. EFFECT: higher efficiency. 1 dwg, 1 tbl
