Reduction roasting-magnetic separation realizes the separation of titanium and iron in high-titanium beach titanomagnetite. However, the TiO 2 grade in titanium concentrate is low, and few studies have investigated low-titanium beach titanomagnetite. The preconcentration-reduction roasting and magnetic separation process was developed to utilize the low-titanium …

For Fe(0.5)-Mn/TiO 2 and Fe(0.7)-Mn/TiO 2, the larger H 2 consumption could be attributed to the higher oxidation state of iron. Based on these results, it is reasonable to speculate that the modification of Fe makes Fe-Mn/TiO 2 catalysts possess a moderate redox ability, which may effectively inhibit the unselective oxidation of NH 3 and ...
