The complexity of the mineralogical, chemical and exogenous parameters generates a low efficiency of electrical separation of oxidized iron ore. For this purpose, a study was conducted to provide a method for electrostatic separation and to select the chemical reagents. And this, for increasing the contrast of the dielectric separating minerals in the corona discharge field. The reagent-collector used is the auramine with a specific consumption of 0.3 kg / t. Whereas the reagent –depressants is carboxymethyl cellulose mixture with a specific consumption of 0.25 Kg / t. From the obtained test results electrical treatment of oxidized iron ore are satisfied for proposed process
