The pelletizing process studies have been performed as to sintering furnace charges from hematite ore of Bolshetroitskoye deposit. It had been determined that increase of pelletizing ability of sintering furnace charge is possible due to lime application as a fluxing additive. But it’s highly restricted because of ore composition peculiarities, particularly due to low grade of silica in ore. An activation of the ore particle surface during its regrinding enables substantial increasing of the pelletized sintering furnace charge quality using hematite ore of Bolshetroitskoye deposit.
