v117n4a7 Recovery of iron from red mud by high

reduction roasting, iron oxides are reduced to metallic iron, which could be upgraded by magnetic separation. Previous research reported that the sodium borate is an effective additive to improve the reduction of iron oxides and the growth of the metallic iron grains (Long et al., 2016). Therefore, sodium borate was employed as an additive in this
