The continuous alteration of ilmenite through
The continuous alteration of ilmenite can be expressed in terms of two reactions: (a) 3Fe 2+ TiO 3 →Fe 3−x 2+ (Fe (2 3)x 3+ + (1 3)x) Ti 3 O 9. In this equation x =0–3; x =0 corresponds to ilmenite, x =3, to pseudorutile. In the range of x =0–2.1 "leached ilmenite" occurs. Reaction (a) is established by oxidation and leaching of iron.
