| Abstract Scope |
The vacuum metallothermic process is the leading method of magnesium production in the world. In this technique, the Mg content of calcined dolomite is reduced with FeSi to obtain crown Mg. Since FeSi production can be carried out with high energy consumption and high CO2 footprint, it is a techno-economic necessity to work on reductants. In this study, the effects of using a product containing 53.50% metallic Al obtained from Al dross as a substitute reducing material. In the experiment conducted for 6 hours at 1300°C, where 150% of the stoichiometric Al addition was used in a vacuum atmosphere, the Mg content in the slag decreased to 5.31%. The amount of Mg remaining in the slag decreased to 2.61% and the highest recovery value achieved in this study was 90.87% with the addition of 5% CaF2 to the charge under similar conditions. |
