Titanomagnetite

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 intrusions in the Duluth Complex. Get price

This ore sometimes contains a composite ore of TiO2 and V2O5, which is called titanomagnetite or strontium titanomagnetite. It is rarely encountered in natural pure magnetite ore, and some of the magnetite is often oxidized into semi-artificial hematite and imaginary hematite due to surface oxidation. Get price

Titanomagnetite

Hardness on Mohs' scale is 5.0–5.5, and the density is 4,800–5,300 kg/m 3. Titanomagnetites are decidedly ferrimagnetic, although ulvospinel is strictly paramagnetic. The two ranges of Curie points characteristic of titanomagnetite are 0–100C (for ulvospinel with an FeFe 2 O 4 content up to 20 percent) and 500–570C (for magnetite with an Fe 2 TiO 4 content up to 10 percent).
