Innovative Utilization of a Borate Additive in Magnesium Production to Decrease Environmental Impact of Fluorides from Pidgeon Process

Abstract:

The present authors have utilized, for the first time, H₃BO₃ as an additive in pilot scale experiments of Mg production using Pidgeon process. The results from the experiments revealed positive effects of H₃BO₃ on both quantity and quality of the Mg metal crowns. Besides acting as a catalyzer for MgO reduction, H₃BO₃ stabilized also β-Ca₂SiO₄ in the Mg slag. Based on these results, H₃BO₃ may be adopted as an innovative additive replacing fluorite in the Mg production, to enhance sustainability and environmental soundness for the Pidgeon process in China.
