Abstract: Hexafluorotitanic acid (H 2 TiF 6) selectively dissolves kaolinite and most other phyllosilicate minerals of soils and sediments, concentrating free crystalline (Ti,Fe)O 2 minerals (partially substituted anatase and rutile) in the residue. A series of H 2 TiF 6 reagents was standardized by analysis of the Ti content and by tests with pure anatase …
