“…In liquid oxidic solutions, in that metallurgic slags, the activity of a solution component depends on its interaction with the remaining components [1][2][3][4][5]. In the case of weak interactions the component is transported towards the surface, thus lowering the surface tension of liquid slag.…”

Surface phenomena play a major role in metallurgical processes; their operation results, among others, from the surface tension of liquid oxidic systems. One of the methods of determining surface tension of oxidic systems is performing calculations with Butler's method. Surface tension was calculated for two-and three-component liquid oxidic systems typical of metallurgical processes. The determined dependence of surface tension in FeO-SiO 2 at temp. 1773 K and CaO-SiO 2 at temp.1873 K showed that with the growing participation of SiO 2 surface tension decreased. Analogous calculations were performed for three-component systems: CaO-Al 2 O 3 -SiO 2 and MnO-Al 2 O 3 -SiO 2 . The results of calculations of surface tension were determined for temp. 1873 K and compared with the results obtained by T. Tanaka et al. [19]. In both cases the increase of Al 2 O 3 content resulted in a growth of surface tension. The simulation results were higher than experimental result, as compared to the literature data.

The results of simulations of Fe recovery from steel slag containing iron oxides with C reducer dissolved in liquid slag and gaseous CO were presented in the paper. The simulations were performed with the use of a commercial program FactSage, and the calculations followed the procedure of dosing the reducer to slag in portions, each time reaching the state of thermodynamic equilibrium. The calculation procedure was realized sequentially, and the equilibrium composition of gaseous phase, nonmetallic phase and separated Fe was established at each calculation step. Gaseous products of CO and CO2 reduction were removed from the system with each successive calculation step. The simulation revealed that reaching comparable results of reduction requires using a considerable amount of CO. Moreover, the CO2 content in the gaseous phase and amount of separated Fe depend on the type of reducer. It was observed that the main mechanism was the reduction of iron with C. In this case the composition of gaseous products was mainly dominated by CO-CO2.
