FIELD: mineral dressing. SUBSTANCE: method includes crushing original ore and consecutive elutration of crushed material into sands and drain. Sands are additionally crushed and returned into elutration process. Drain is deslimed and subjected to magnetic dressing to yield magnetic product and tails. From the feed of the last step of magnetic dressing, a fine fraction is separated which is further deslimed to yield concentrate and tails. Concentrate is combined with magnetic product and filtered. Deslimed product from preceding step is subjected to elutration to produce granulated and fine fractions. The latter is combined with drain from subsequent elutration step. EFFECT: enhanced efficiency of process. 1 dwg
