Beneficiated Ilmenite (BI) is the material for the Pigment Production Plant. BI from Ilmenite Beneficiation Plant is chlorinated in the Chlorination Plant to produce Titanium Tetra Chloride (Tickle). Chlorine reacts with Titanium Dioxide and other metallic oxide impurities in BI in the presence of petroleum coke at a temperature of 9000C in
Raw ilmenite is refined by decreasing the iron content. Carbon (anthracite) is used to convert some of the iron oxide in the ilmenite to metallic iron. The products of this process are molten iron (pig iron) and a slag rich in titanium. Ilmenite sand is also used as a sandblasting agent in the cleaning of diecasting dies.
The Ilmenite liberation degree was determined by using grain counting method by reflected microscope (Table 3). The separation tests were performed by three methods such as hand panning method, gravitational separation by shaking table method and magnetic separation method. Table 3.

Low grade ilmenite cannot be treated by this method since all silicates and insoluble matter will contaminate the product. The synthetic rutile is then treated by chlorine to prepare TiCl4 from which TiO2 or titanium metal are obtained without pollution problems. Ilmenite for pigment and metal production
An ilmenite ore may be beneficiated by converting the ore into a pseudobrookite-containing material, reducing that material to give a product having at least 4% of its iron content in the ferric state, and finally leaching the reduced product. Leaching is facilitated by the previous two steps.

Though hematite (ferric iron) has higher specific gravity, it has higher grindability and, hence, in the process of crushing and
Consequently greater emphasis is being laid on developing a process for physical and or chemical beneficiation of natural ilmenite to a synthetic rutile containing more than 90% titanium dioxide. Various processes for beneficiation of ilmenite have been reviewed in the literature particularly by Kothari.' The present paper describes a simple method of beneficiation by selective chlorination of natural ilmenite in a fluidised bed. 2. Experimental 2.1. With chlorine alone Initial experiments
The Manufacturing Plant at KMML comprises the Mineral Separation Unit and the TP Unit (Ilmenite Beneficiation Plant, Acid Regeneration Plant, Pigment Production Plant, Oxygen Plant & Utility Section). The Ilmenite obtained from the Mineral Separation Unit is taken to the manufacturing facility for further processing.

Ilmenite in ultramafic lamprophyre ore occurs in various forms such as Ilmenite grains, exsolved Ilmenite lamellae in phlogophyte and Ilmenite particles disseminated in silicate minerals. The feasibility of physical separation has been performed for mineral beneficiation. The grain forms liberated in 63µm-1000µm are recoverable by physical methods. The maximum content of TiO 2 in Ilmenite lattice is determined 54.62% by EPMA. Although the ore has 6.37% average grade of TiO 2 , the
The process includes reduction of ilmenite concentrate using anthracite coal as reductant, followed by aeration of reduced ilmenite in ammonium chloride solution (NH 4 Cl). The controlled parameters were temperature and NH 4 Cl concentration. The results showed that the degree of iron metallization was 83% after 4 hours of reduction at 1150 °C.
Combination beneficiation ilmenite digestion liquor reduction process This is a distinct advantage over other beneficiation processes. The iron in the ilmenite ore which has not been reduced to the metallic state is generally in the form of the ferrous oxidation state.
Concentrates containing rutile, ilmenite, magnetite, zircon and possibly silica are sized over a vibrating screen and collected in separate storage hoppers ahead of dry processing, as each size is treated separately. Low intensity magnetic separation pulls out metallic iron and magnetite.
Ilmenite mining process Most ilmenite ore are poor ilmenite ore, so the ore processing must be carried out. Ilmenite ore beneficiation methods currently used for the mechanical selection including washing, screening, reelection, high intensity magnetic separation and flotation, as well as fire enrichment, chemical processing method.
