ELECTRO SMELTING OF ILMENITE FOR PRODUCTION

4.1. TiO2 Slag Ilmenite smelting is a carbothermic process to upgrade the mineral ilmenite, yielding TiO2-rich slag (which is mainly used as a feed stock for TiO 2 pigment production) as primary pr oduct and pig iron as a by-product. This smelting process is unusual in having slag as its primary product and metal as a by-product. Another

A Review of the Production Cycle of Titanium Dioxide Pigment

The sulphate process was the first commercialized technology to obtain the titanium dioxide pigment. In this process, ilmenite (40% - 60% TiO 2) or titanium slag (72% - 85% TiO 2) or even a carefully controlled blend, is digested with concentrated sulphuric acid (98%). A highly-exothermic reaction is initiated by the addition of measured
