ILMENITE (Iron Titanium Oxide) - Amethyst Galleries

Ilmenite is an economically important and interesting mineral. It is named for its place of discovery (such places are called type localities) at Ilmen Lake in the Ilmen Mountains, Miask in the southern portion of the Ural Mountains of Russia. Ilmenite forms as a primary mineral in mafic igneous rocks and is concentrated into layers by a process called"magmatic segregation".

THE CONCEPT MAGNETIC MINERAL SEPARATION

2019-8-1  The E roast produced some very interesting magnetic changes within the ilmenite particles, in that the magnetic susceptibility of the ilmenite wasnotsignificantly increased bythe roast, butthe mag-netic rotatability ofthe particles wasgreatly increased. This points to a roast-induced change of only the structure of ferromagnetic com-

Magnetization of exsolution intergrowths of hematite

1. Introduction [2] The hemo‐ilmenite ores from the Allard Lake area, Quebec, have been of interest for their magnetic properties since the 1950s [Hargraves, 1959a; Carmichael, 1961].Nearly 50 years later, Hargraves' interest was rekindled in these rocks with the discovery of magnetic anomalies on Mars and with the concept of lamellar magnetism [Robinson et al.,

University of Minnesota’s Mineral Pages: Calcite

Ilmenite: Ilmenite is a dense, black metallic mineral that, when rubbed across a rough hard surface, exhibits a black streak similar to that of magnetite. As ilmenite is not magnetic, a magnet can be used to distinguish pure samples of the two. Some ilmenite samples appear weakly magnetic, however, due to inter-grown magnetite crystals.

Magnetic Susceptibility – Science 304

The ratio between applied magnetic field and a material’s (induced) magnetization is called magnetic susceptibility. It is given the symbols k, κ, or χ. If you were to measure magnetic susceptibility carefully, you could identify differences between these minerals – perhaps even between the different orientations of the mica.
