It is apparent that high-gradient magnetic separation plays the most significant role in the flowsheet for the production of qualified high-grade ilmenite concentrate, by providing a primary ilmenite concentrate to the reverse flotation flowsheet, at a low mass flow rate.

As it cools, crystals of ilmenite will begin forming at a specific temperature. These crystals are heavier than the surrounding melt and sink to the bottom of the magma chamber. This causes ilmenite and similar-temperature minerals, such as magnetite, to accumulate

Magnetite is also similar and easily confused with ilmenite, but ilmenite has a different crystal form and is not as strongly magnetic. It is often associated with magnetite and therefore ilmenite is a minor ore of iron as the magnetite and ilmenite are processed for their iron contents.

2021-6-5 Ilmenite (an iron-titanium oxide) and rutile (a titanium oxide) are the most commonly mined materials containing Titanium. Both are extracted from salt and Titanium is separated from other materials. Some properties like high tensile strength, high

2020-6-6 Ilmenite is weakly magnetic mineral sand, grey-black in colour, solid in form and exists in a triangle crystal structure. On the other hand, rutile is reddish-brown and exists in a tetragonal crystal structure. These heavy mineral sands are excavated and dredged, mostly to commercially produce ilmenite, rutile or other titanium oxide ores.

2010-6-26 The ilmenite-hematite (FeTiO3-Fe2O3) solid solution is one of the most important magnetic phases in nature. Unusual magnetic behaviour is often observed in intermediate compositions due to the interaction between cation ordering, magnetic ordering, and exsolution. This presentation describes how this interaction leads to the phenomenon of

Fortunately only a few minerals occur abundantly enough in nature to make a significant contribution to the induced and remanent fields. The most important of these is magnetite and to a lesser extent ilmenite and pyrrhotite [3].

2017-6-26 Magnetic separation is used to separate the magnetic minerals (ilmenite and monazite) from the non-magnetic minerals (rutile and zircon). This removes oxygen from the ore and produces metallic iron within the ilmenite.

2021-6-3 Ilmenite is slightly magnetic, which means that magnets can be used to separate it from other minerals in sand deposits. It is able to withstand extreme temperatures and is used in the steel industry to line blast furnaces. Ilmenite's hardness also makes it useful as an abrasive. Ilmenite is the main source of titanium

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-

2012-1-23 The magnetic properties of fresh and metamorphosed gabbros appeared to be similar. The majority of gabbros studied were characterized by median destructive fields greater than 200 Oe. The high stability is attributed largely to the effective subdivision of the magnetite grains by the ilmenite

2021-6-5 Titanium is weakly attracted to magnets as it is a paramagnetic material. The main reason for its paramagnetic nature is its electronic configuration with 4 unpaired electrons, as paramagnetism depends on unpaired electrons. The second reason is its magnetic

2007-10-30 Below the ilmenite AF ordering T, magnetic saturation properties are dominated by phase transitions of ilmenite. At and below 40 K, ∼ where ilmenite two-layer ordering is expected, the measurements are complicated by exchange interactions shown by shifted hysteresis loops of up to 40 mT. The exchange coupling leading to exchange bias is an ...

The fact that the natural remanent magnetization (NRM) intensity of mid-oceanic-ridge basalt (MORB) samples shows systematic variations as a function of age has long been recognized: maximum as well as average intensities are generally high for very young samples, falling off rather rapidly to less than half the recent values in samples between 10 and 30 Ma, whereupon they slowly rise in the ...

2015-4-24 Process widths are usually 1m to 1.5 m, with 2-4 magnetic stages. In a rare earth roll, material is fed evenly on its separator belt and is transported over a uniquely designed magnetic roll. As the feed material moves through the magnetic field, all magnetic particles are attracted to the roll.
