Abstract Currently the most common fluxing additive to pellets is dolomite CaCO3 · MgCO3 in which the magnesium oxide content can form from 17 to 22% If the magnesium oxide in pellets increases then it is necessary to increase the dolomite dosage Thus the iron content decreases which entails a decrease in yield ratio at subsequent processing One of the fluxes containing magnesium is
