Abstract
From the results of reduction smelting of agglomerated cakes from leaching mixtures of greasy mill scale (GMS) with 75 and 100 % of red mud (RM) and fired pellets made from these agglomerated cakes, the possibility of selective separation of Fe, P and Ga in pig iron, and Al2O3, TiO2, Sc2O3 – in slag suitable for cement production has been established. We found that, depending on the melt holding period (20–60 min at temperature of 1620 °C), the following elements (in %): 98 Fe, 22–66 Si, 1 S, 99 P, 11–20 Ti, 98–99 Ga pass into pig iron. The compounds (in %): 95–99 Al2O3, 55–65 SiO2, 88–90 TiO2, 98–99 Sc2O3 are concentrated
in the slag. The process flow diagram of GMS and RM joint utilization has been developed.
