Abstract. Titania-rich slags with 80 mass percent TiO 2 are produced in the electric arc furnaces of QIT-Fer & Titane, Inc., by the continuous smelting of hemo-ilmenite ore with anthracite coal. Titania slag represents an important feedstock for the manufacture of titanium dioxide pigment by the sulphate process.

Ilmenite, metallized ilmenite and slag show different morphologies and microstructures. The separation of both Ti and Fe from a combined state (as seen in ilmenite) improved with the degree of metallization. Metallized ilmenite and slag show different distribution patterns of major phases, such as Ti, Fe and minor impurities like Mg, V and Al.

The as-received ilmenite concentrate contained about 85% of the material in a size range of 125 to 250 µm. Hence, to generate the feed for pelletization, the concentrate was milled in a laboratory-scale ball mill. The particle size distribution of the ground concentrate is shown in Fig. 3. The ground ilmenite concentrate having 80% of the mate-

Ilmenite is usually sold on NAW (naked at works) basis from all production center. PRODUCTION AND PRICES Ilmenite The production of ilmenite at 285 thousand tonnes in 2017-18. Rutile The production of rutile at 11.82 thousand tonnes in 2017-18. Production and prices of ilmenite and rutile are furnished in Tables -2 to 4.

The review of some new processes currently under development clearly shows that iron recovery is essential for the long-term viability of any new ilmenite upgrading or TiO2 pigment production process.

Ti and Fe based products. It is economically beneficial to add value to the ilmenite mineral because large scale industries utilize ilmenite as the raw material for products use in environmental remediation, energy production, synthesis of pigments, etc. This review provides a comprehensive and comparative account of the main analytical

Ilmenite is either used directly as feed stock for titanium dioxide (TiO2 production processes or it is pre-treated to produce titanium slag and synthetic rutile that are further used as feed stock …

Nitriding of ilmenite and high-grade T slag fines SciELO. Two TiO2 feeds were used, i.e. ilmenite and CG slag fines. The analyses of these materials are given in Table I and II. The particle size of the ilmenite ranged between 46 and 212 μm with an average of 117 m.
