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

2020-10-28 · 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
