- manganese ore ilmenite
Ilmenite has high iron content, whereas the other two OC, Sibelco braunite and another manganese ore (Mn ore) of unknown origin, came with higher manganese contents. An advantage of these two OC is the oxygen uncoupling ability (CLOU), which is a known effect for some manganese ores.

As shown in Table 1, the chemical analysis of high-iron red mud and high-manganese iron ore indicates that the iron content of red mud is ω (TFe) = 49.11%, much higher than the average iron grade of ω (TFe) = 32.60% in China's iron reverse. The content of Al 2 O 3 and SiO 2 is 8.36% and 4.63%, respectively. The iron content of high …

Manganese ore is required in iron making to control the manganese content of the hot metal in the desired range. Unlike other plants, where manganese ore lump is used directly in blast furnace, in VSP, it was proposed to use manganese ore fines in sinter productions. This would ensure much more consistent manganese content in the hot metal.

Ilmenite is a combined oxide naturally occurring in the form FeTiO3, which is also the reduced form in CLC. The oxidized form is Fe 2 TiO 5 + TiO 2. It has also been shown that there is a migration of Fe to the surface; thus in practice ilmenite is in part an iron oxide material ( Adanez et al., 2010 ).

Two natural materials were chosen as oxygen carriers in this study, a Norwegian ilmenite and a Brazilian manganese ore. Ilmenite, FeTiO 3 (reduced form), is a weakly magnetic iron–titanium mineral which is produced in large quantities worldwide.

Ilmenite is one of the most significant ore s of the metal titanium. It is mined as an important industrial mineral in several deposits throughout the world. Many of those deposits are in heavy placer sands. Ilmenite is very similar in structure to Hematite, and is essentially the same as Hematite with roughly half the iron replaced with titanium.
