Description: Calcium aluminate fluxes have been used for the treatment of hot metal and liquid steel. These fluxes can be produced from three different raw materials: (1) high-quality bauxite, (2) residuals of aluminum dross treatment and (3) white mud from alumina production. From an environmental-friendly perspective, the latter two sources are preferred. As fluxes made from dross have already been used in industry, the main objective of this project is to examine the use of white mud as a new potential desulphurization reagent. X-Ray Diffraction and Thermogravimetric Analysis were used to study the dehydration process of white mud. Drip tests and desulphurization experiments were carried out to compare the melting rate and desulphurization performance of white mud fluxes with those of fluxes made from bauxite and dross. The results show that the white mud fluxes have the highest melting rate and the best desulphurization performance.
