FIELD: mining. ^ SUBSTANCE: method of mineral dressing includes material separation in air flow in chamber pneumatic separator with extraction of concentrated product, middlings and tail product. Tail product extraction is performed with its subsequent pneumo-cyclonage, whereupon tails of pneumo-cyclonage are sent to dump waste product, and dressed product is forwarded to recleaning operation together with middlings of pneumatic separation, obtaining rich product and poor middlings forwarded to head of primary pneumo-cyclonage. Rich product of recleaning operation of pneumo-cyclonage is forwarded to refining together with concentrated product of pneumatic separation. ^ EFFECT: enhancement of dressing process quality and improvement of extraction of useful component and of dressing conditions. ^ 2 cl |
