T ilmenite smelting based on CO2 - SciELO
The first step in upgrading the ilmenite to a pure TiO2 product is smelting the ilmenite to produce a TiO2 rich slag of 80-90% TiO2 content. During ilmenite smelting, the iron content of the oxide is lowered by reduction to metallic iron, which takes place in the liquid state at temperatures around 1650°C. This process produces two products, a
