The objective of this paper is to present an analysis of the use of residual marble mixtures in the pig iron desulfurization process. The study involved the use of: marble waste, fluorspar, lime, and hot metal. Four mixtures were made and added to a liquid hot metal - with known chemical composition - at a temperature of 1450ºC. The mass of each element was calculated from its chemical analysis and compared with an industrial mixture. All of the four mixtures used in the experiments were stirred by a mechanical stirrer. Samples were collected by vacuum sampling for times of 5, 10, 15, 20, and 30 minutes, and analysis was performed to check sulfur variation in the bath with time. The results were analyzed and they verified that it was possible to use marble waste as a desulfurizer.

To explore the feasibility of hot metal desulfurization using red mud, the sulfur distribution ratio (LS) between CaO-SiO2-Al2O3-Na2O-TiO2 slag and carbon-saturated iron is evaluated in this paper. First, the theoretical liquid areas of the CaO-SiO2-Al2O3 (-Na2O-TiO2) slag are discussed and the fluxing effects of Al2O3, Na2O, and TiO2 are confirmed. Then, LS is measured via slag-metal equilibrium experiments. The experimental results show that LS significantly increases with the increase of temperature, basicity, and Na2O content, whereas it decreases with the increase of Al2O3 and TiO2 content. Na2O in the slag will volatilize with high temperatures and reducing conditions. Furthermore, based on experimental data for the sulfur distribution ratio between CaO-SiO2-Al2O3-Na2O-TiO2 slag and the carbon-saturated iron, the following fitting formula is obtained: log L S = 45.584 Λ + 10568.406 − 17184.041 Λ T − 8.529
