Upon oxidation of ilmeinte, mtile cml be formed wiffl modest energy consumption; furfflermore, after leaching, only a few byproducts are formed. Unfortunate- ly, one drawback is file necessarily long oxidative process of typically used mefflods. In fflis study, we show fflat a fluidized bed reactor cml be used to oxidize ilmeinte ore to rapidly form ruffle mid pseudobrookite （Fe2TiOs） phases. Ilmeinte was oxidized wiffl 5vo1% 02 in Ar at temperatures of 1173 K or 1223 K mid subsequently leached using a diluted H2SO4 solution to dissolve file pseudobrookite phase. The effects of acid concentration, temperature, mid cooling rate after oxidation were investigated. We show fflat file ilmeinte was rapidly oxidized to form rutile mid pseudobrookite phases at 1173 mid 1223 K in a 5vo1% O2/95vo1% Ar environment wifflin 40 min. The fmal maximum mtile yield was 84.2mo1% after leaching in （1 ＋ 1） H2SO4 solution at 393 K for 12 h.展开更多
