Abstract: 
Technological parameters of concentrates obtained using developed approaches and conventional methods of beneficiation were determined. It was shown, that parameters of concentrates obtained by developed approaches, are higher than those obtained by conventional methods, wherein, iron concentration in concentrate was 70.6 and 65.42%, respectively, and iron losses in tailings were 2.9 and 22.02%, respectively.
