Effect of Flumag M Flux on Strength Properties of Iron Ore ...

Oct 28, 2020  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
