Catalyst can enhance the reduction effect and promote of vanadium titanomagnetite. In this paper, carbon-containing pellets titanomagnetite were prepared by using highly volatile coal as reducing agent under background a novel process pre-reduction in rotary kiln. The effects CaO, CaCO 3 , B 2 O borax (Na 4 7 ·10H O) on tail gas characteristics prereduction studied simulated kiln flue analyzer....

[1] A series of four synthetic basalts comprising titanomagnetite (Fe3-xTixO4) grains of varied size and titanium content have been produced by a glass-ceramic method. Complementary characterization techniques of X-ray diffractometry, secondary electron microscopy, and transmission electron microscopy (TEM) demonstrate the reaction product composition consisted of mainly Fe3xTixO4, pyroxene hed...

The Raman spectral patterns of analyzed natural titanomagnetite samples revealed peaks at 670-680 cm-1, 544-603 407-495 cm-1 and 373-392 that correspond to the A1g, T2g (2), (3) Eg vibrational modes spinel Fd3m space group. Previous studies spectra have suggested behavior these reflect distribution Fe2+-O, Fe3+-O Ti4+-O bonds within crystal structure. peak intensities each are observed be relat...
