The problem of utilization of iron ore tailings . The prospects of iron ore mining in the Russian underground . A method for extracting iron from tailings to 9 % of the original content, by mechanochemical processing. The results of particle size distribution , chemical and mineralogical analyzes of samples collected waste ferruginous quartzites LGOK . Experiments were carried out using the methods of planning optimal experiments , Box-Behnken and included 24 experience. Obtained according to the content of metal recovery in the leach solution of sulfuric acid , sodium chloride , rotor speed and the ratio of disintegrant liquid and solid phases. This dependence allows to determine the optimal parameters of technology in terms of " metal recovery ." The resulting secondary processing of tailings to be used in the manufacture of hardening mixes for stowing as an inert filler and binder counterpart .

Keywords: tailings, mechano-chemical activation, iron ore, ferruginous quartzites, metal recovery
