Sulfide capacity modeling of FeOx-MO-SiO2 (MO=CaO, MnOx, MgO) melts

Minerals & Metallurgical Processing, 2011, Vol. 28, No. 1, pp. 33-36

Darin, B.; Yucel, O.M.S.; Reddy, R.G.

ABSTRACT:

 In this study, the Reddy-Blander model was applied to predict the sulfide capacity (CS) values of FeOx-CaO-SiO2, FeOx-MnOx-SiO2 and FeO-MgO-SiO2 ternary slags, which were experimentally studied in the literature within the temperatures between 1,673 and 1,923 K. As expected, sulfide capacity values of the slags increased with increasing temperature and decreased with increasing acidic content. The model was found to be in agreement for all slag systems at the temperature range of 1,773-1,923 K. However, a disagreement occurred when the basic content was relatively high, at 1,673 K for FeOx-CaO-SiO2 and FeO-MnOx-SiO2 slags. The effect on the CS of high amounts of Fe+3 and Mn+3 in the slags is discussed.
