Titanomagnetite Article about Titanomagnetite by The ...

Dec 14, 2010  Titanomagnetite contains admixtures of Al 3+, V 4+, Gr 3+, and Mn 2+. It occurs as octahedral crystals and, more frequently, granular aggregates and black masses. Hardness on Mohs’ scale is 5.0–5.5, and the density is 4,800–5,300 kg/m3. Titanomagnetites are decidedly ferrimagnetic, although ulvospinel is strictly paramagnetic.

Titanomagnetite - an overview ScienceDirect Topics

The principal ore minerals are titanomagnetite and ilmenite, which may occur as euhedral primocryst grains or filling interstices between silicate minerals (Fig. 3.17). Large resources of TiO 2 exist in these small intrusions; Hauck et al. (1997) estimated resources of as much as 245 million tons of ore with greater than 10% TiO 2 for the ...
