Abstract
The possibility of the selective separation of components of starting materials with concentrations of Fe, P, and Ga in cast iron and Al2O3, TiO2, and Sc2O3 in slag suitable for cement production is established based on the results of reduction smeltings of cakes after leaching the mixtures of greasy mill scale (GMS) with 75 and 100% red mud (RM) and fired pellets made of these cakes. It is shown that, depending on how long the melts were held (20–60 min at 1620°C), the components are transferred into cast iron: 98 Fe, 22–66 Si, 1 S, 99 P, 11–20 Ti, and 98–99% Ga. Components that are concentrated in slag are 95–99 Al2O3, 55–65 SiO2, 88–90 TiO2, and 98–99% Sc2O3. A flowchart of the joint utilization of GMS and RM is developed.
