Ilmenite for pigment and metal production

Titanium slag is mainly iron magnesium titanate, (Fe,Mg)Ti4O10, and a small amount of silicates; typical analyses is 7285% total TiO2. A small amount of TiO2 is reduced to Ti2O3. The reduction of the iron oxides is not taken to completion so that some iron oxide is left in the slag to decrease its melting point.
