The process generates very little in the way of waste products. The ilmenite (FeTiO 3) is partially reduced with char to yield a low-manganese iron, a slag containing 85 per cent TiO 2 (which is the primary product) and a gas containing roughly 85 per cent CO and 12 per cent H 2 according to the reaction: FeTiO 3 + C = TiO 2 (l)+ Fe (l)+ CO (g).

Ilmenite for pigment and metal production - OAText

The process naturally can be applied to high grade ilmenite. It bypasses electric furnace process which applies only to high grade ilmenite and is superior to the sulfuric acid process which is highly pollutant. The product of this process can be used to prepare the white pigment as well as titanium metal.

For these reasons, titanium slag was used only for making pigment by the sulfuric acid process [7]. The slag was treated in the same way as ilmenite with the exception that no separation of ferrous sulfate was necessary because the bulk of iron was already separated by reduction in the earlier step (Figure 13).

Ilmenite smelting: the basics T - SAIMM

In ilmenite smelting, the iron content of the oxide is also lowered by reduction to metallic iron, but this takes place in the liquid state, at a much higher temperature (of around 1650°C). Ilmenite smelting thus yields two products: a titania-rich slag, and molten iron. This is in contrast with the Becher process,
