The ore is first calcined and the resulting magnesium oxide is converted to magnesium chloride by leaching with an ammonium chloride solution. Calcium chloride is also produced at the same time.

Currently, the South African based producers of titanium dioxide (TiO2) feedstock produce TiO2 slag via the smelting of ilmenite, involving the carbonaceous reduction of ilmenite to achieve a slag with a TiO2 content of around 85%, and a high-purity pig iron as co-product.

Wet grinding method, which is often used to reduce particle size and improve the balling ability of ilmenite, was proposed to enhance the reduction. The effect of wet grinding on the carbothermic reduction of ilmenite was investigated. The wet grinding treatment was found to result in a high reduction rate and improve metallisation.

1. Introduction. As natural rutile and high-grade titania mineral resources decrease worldwide, ilmenite has become one of the important raw materials for the titanium industry because of its titania content (Wu and Zhang, 2006, Pistorius and Coetzee, 2003).Grades of ilmenite contain 45 to 65.8 mass percent TiO 2 and ilmenite is regarded as a significant resource in the production of rutile ...
