Chemistry and Mineralogy of Titanium-rich Slags

crude titania-rich slag is further acid-leached under a high-pressure and moderate-temperature hydrometallurgical process to yield an upgraded titania slag with 94.5 mass percent TiO 2. The chemistry and mineralogy of these synthetic titania-rich feedstock's is unique among other industrial products and relatively complex due to several factors.

As a result of the reduction smelting of the titano magnetite concentrate, the slag has a high iron content and concentrates more than 90% vanadium along with titanium [1, 2]. The use of a CaCO 3 addition during smelting leads to the formation of the second (along with iron oxide) unstable component in the slag, namely, calcium oxide. The iron ...

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,
