Magnetic properties of ilmenite, hematite and oilsand ...

Ilmenite, hematite, and a rutile concentrate (LR Rutile) produced from the oil sands tailings (containing mainly leucoxene and rutile), were used in the study. It was observed that the magnetic susceptibility of ilmenite increased after either oxidation or reduction roasting

01-12-2002  Test results indicated that oxidation roasting of the ilmenite could increase its magnetic susceptibility within a certain temperature range. As can be seen from Fig. 1, Fig. 2, at 500 °C, even extended heating (up to 2 h) did not cause any change in the magnetic susceptibility of the ilmenite.At higher temperatures (650 and 700 °C), its magnetic susceptibility started to increase after ...

Ilmenite - chemeurope

Ilmenite is weakly magnetic, with its response to a hand magnet weak. Mineral chemistry Although there appears evidence of the complete range of mineral chemistries in the (Fe,Mg,Mn,Ti)O 3 system naturally occurring on Earth, the vast bulk of ilmenites are restricted to close to the ideal FeTiO 3 composition, with minor mole percentages of Mn and Mg.

Ilmenite - Wikipedia

Ilmenite, also known as manaccanite, is a titanium-iron oxide mineral with the idealized formula FeTiO 3.It is a weakly magnetic black or steel-gray solid. From a commercial perspective, ilmenite is the most important ore of titanium. Ilmenite is the main source of titanium dioxide, which is used in paints, printing inks, fabrics, plastics, paper, sunscreen, food and cosmetics.

Thus, most of the magnetic remanence of the Allard Lake ferrian ilmenite in Carmichael's work, and by analogy, also in our samples, must be due to large titanohematite lamellae hosting the smaller ilmenite lamellae.By this reasoning, the effective size of the titanohematite carrying the remanence perpendicular to c axis (Carmichael, 1961) is between 0.2 and 0.4 mm.

22-02-2005  We therefore, studied the magnetic properties of FeTiSi and FeTiSi 2. For the magnetic measurements, FeTiSi and FeTiSi 2 alloys were prepared by arc-melting and subsequent annealing at 1273 K for 24 h in an argon atmosphere since the Fe–Ti–Si alloys produced by direct reduction of ilmenite contained some other phases.
