Iron ore beneficiation technologies in Russia and ways to improve their efficiency

Increasing the efficiency of crushing circuits is associated with a decrease in particle size finely crushed ore and use dry magnetic separation ore. Reducing grinding costs achieved by using drum mills jointly other designs. The automation systems, slurry demagnetization, technologies staged concentrate separation, beneficiation fine screening closed cycle lead to reduction costs. main industrial technology for improving quality its additional regrinding, screening, flotation, magnetic-gravity separators. integrated iron raw materials an increase yield production hematite during hematite-magnetite ores ilmenite titanomagnetite ores. Incremented possible separators increased induction up 0.25-0.5 T first stages beneficiation. To obtain concentrates, combined can be used, including high-gradient magnetic, gravity, electrical separation.
