    Extraction of Iron from Vanadium Slag Using Pressure Acid

    Jan 01, 2016 The extraction of iron from vanadium slag was attempted using pressure acid leaching. The effects of the several parameters which included reaction time, H + /slag ratio, leaching temperature, and concentration of additive (Na 2 S) upon leaching efficiency of iron were investigated. The results showed that the leaching efficiency of iron could reach above 76% in
