FIELD: iron ores enrichment. SUBSTANCE: method involves origin material sorting, grinding and desliming. Deslimed material is affected by magnetic separation to prepare magnetic product and tails, deslimed material being affected by additional sorting to produce fine fraction. The latter is fed for additional desliming to prepare concentrate and tails. Thus prepared concentrate is combined with magnetic product. EFFECT: improves efficiency of the method. 2 dwg
