Dissolution behavior of Li, Ga, and Sc in roasted high-sulfur bauxite during the Bayer process

This data is about the effect of roasting desulfurization process on the leaching behavior of alumina, lithium, gallium, and scandium. the different characteristics methods such as XRD, FTIR, TGA, and SEM of raw bauxite and roasted are uploaded, also the gravimetric methods for total sulfur determination data and finally the leaching behavior alumina, lithium, gallium and scandium under various conditions of roasting process and leaching are also uploaded. the results show data the roasting process can significantly improve the leaching efficiency of valuable elements.
