Among them, OA is vanadium-titanium magnetite con- taining 12.22 wt.% TiO 2. OB, OC, OD, and OE are the iron ores, which are commonly used in sintering plants. The spent SCR catalysts were provided by a coal-fired power plant in China. Table 2 lists the chemical compo- sitions.

Chromium-bearing vanadium-titanium magnetite (CVTM) iron ore containing Fe, Ti, Cr, and V is a special and valuable iron ore as known by the exploitation of vanadium-titanium magnetite (VTM), ilmenite, and chromite [ 1, 2 ]. As a kind of valuable iron ore resource, Hongge CVTM is found in the Panzhihua area in China.

titanium magnetite tio. ... 2014113 ensp 0183 enspvanadium−titanium magnetite concentrate is more complied than other common ores requiring higher temperature and longer reduction time to achieve a relatively high metallization ratio 9 Hence it is important to investigate the reduction kinetics and mechanism of the vanadium−titanium ...

Titanium-bearing magnetite ore is generically defined as magnetite with > 1% titanium dioxide (TiO 2) and is usually vanadium-bearing. The iron and titanium occur as a mixture of magnetite (Fe 3 O 4) and ilmenite (FeTiO 3) with vanadium oxide usually occurring within the solid solution of the titanium-bearing magnetite phase.

magnetite ore and the productive deposits are briefly described below. Vanadium can be recovered from titaniferous magnetite ore or a magnetite concentrate of the ore by either of two general processes. In one process the ore or concentrate is mixed with a sodium salt and roasted, which yields a water-soluble sodium

The sintering pot test was used to investigate the effect of TiO 2 on the sintering behavior of chromium-bearing vanadium-titanium magnetite (CVTM) sinter. The main characterization methods of X-ray fluorescence (XRF), X-ray diffraction (XRD), scanning electron microscopy-energy disperse spectroscopy (SEM-EDS), and metallographic microscopy ...

Titanomagnetites are common magnetic minerals in igneous and metamorphic rocks. Titanomagnetites (Fe3 −x Ti x O 4, 0 ≤ x ≤ 1) form a complete solid solution above ~ 923 K between end-members magnetite (Fe 3 O 4, x = 0) and ulvöspinel (Fe 2 TiO 4, x = 1).

Aluminum oxide ( Al2O3 ) powder for green sand mold coatings is a product of fused corundum produced by melting high-purity alumina powder at a high temperature in an electric arc furnace ( melting temperature is up to 2050 degrees). Then after solidifying, agglomerating, and cooling, it forms to high purity fused corundum blocks.

Hematite was reduced stepwise to form metallic iron. The migration of main titanium components in VTM pellets was obtained as follows: Fe 2 TiO 5 → Fe 3-x Ti x O 4 → FeTiO 3 → Mg x Ti 3-x O 5 and TiC. Most of the titanium element will enter the slag phase. (3) Wustite was an important component during the softening and melting process.
