A method for benefication of magnetic ores includes breakage of initial material, its crushing in the mill of wet self-grinding, screening in the trommel, with supply from the trommel of coarse size into the ore pebble mill, and fine size with pulp - into the spiral classifier, screening of crushing product from ore pebble mill in additional trommel with delivery from the additional trommel of worn pebbles into the mill of wet self-grinding, supply with pulp of fine size from additional trommel and classifier for wet magnetic separation. From the classifier coarse size is supplied to the ore pebble mill. Crushing primary material in the mill of wet self-grinding-screening is carried out in two-sieve trommel, from which intermediate size is divided into two flows, one of which is returned to the mill of wet self-grinding, and the second flow is supplied into the ore pebble mill. The separation of intermediate size into two flows is carried out under condition of guaranteeing the maximumpermissible load of ore pebble mill.
