    Ilmenite - Wikipedia

    Ilmenite, also known as manaccanite, is a titanium-iron oxide mineral with the idealized formula FeTiO 3.It is a weakly magnetic black or steel-gray solid. From a commercial perspective, ilmenite is the most important ore of titanium. Ilmenite is the main source of titanium dioxide, which is used in paints, printing inks, fabrics, , , sunscreen, and cosmetics.

    Testing Of Iron Oxides As Weight Materials For Muds

    Three types of iron oxides, hematite, ilmenite, and Fer-O-Bar are compared with brite as weight material. The specific gravity was 4,54 - 4,68 g/cm3 compared to barite with 4,37 g/cm3. The iron oxides are soluble in HCl in contrast to barite. They were all tested in water and oil based mud, and the rheological properties were satisfactory.

    ILMENITE (Iron Titanium Oxide)

    Ilmenite by itself is not a profitable iron ore as the titanium inhibits the smelting process. Ilmenite, hematite and corundum all have similar structures and belong to a more or less informal group called the Hematite Group with a general formula of A 2 O 3. The structure is composed of alternating layers of cations and oxygens.

    There is an abundant source of raw titanium oxide such as rutile and ilmenite in the Earth’s crust; however, these oxides are thermodynamically more stable (i.e. high enthalpy of formation of its oxide) than other commodity metal oxides such as alumina and iron oxides. Therefore, it is more difficult to extract Ti from its oxide, which is a

    Haaland et al. (1976) compared hematite, ilmenite and FER-O-BAR with barite (Table 1). The specific gravity of iron oxide is higher than barite, which means to achieve the same density, less weighting materials can be used. The hardness and abrasivity of iron oxide are higher than barite, which may add additional cost to the drilling process.
