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.

Crystal class: Rhombohedral (3), H-M symbol: (3)

Ilmenite: An ore of titanium | Uses and Properties

What is Ilmenite? Ilmenite is a common accessory mineral in igneous rocks, sediments, and sedimentary rocks in many parts of the world. Apollo astronauts found abundant ilmenite in lunar rocks and the lunar regolith. Ilmenite is a black iron-titanium oxide with a chemical composition of FeTiO 3.. Ilmenite is the primary ore of titanium, a metal needed to make a variety of high-performance alloys.

Modification of ilmenite surface properties by superficial ...

This is more insoluble than ferrous iron oleate. The insolubility of this hydrophobic layer would result in the improvement of ilmenite flotation recovery. Consequently, the superficial dissolution is a reliable and preferred process for the modification of ilmenite surface properties and improvement of its floatability.

Influence of microwave irradiation on ilmenite surface ...

In this study, the effect of microwave irradiation on ilmenite surface properties and its flotation behavior was investigated. After microwave irradiation, Fe 2+ ions on the ilmenite surface are oxidized to Fe 3+ ions. XPS analysis indicated that the relative content of Fe 3+ increased from 48.5% to 66% after microwave irradiation for 2.5 min. This conversion decreased the ilmenite surface ...

Effect of surface dissolution on kinetic parameters in ...

As confirmed by contact angle measurements, this prevents the formation of a stable hydrophobic layer on the minerals surfaces for creating stable attachments between minerals and bubbles. Generally, the improvement of ilmenite flotation kinetics has a negative correlation with the iron content in its accompanied gangue minerals.

ILMENITE (Iron Titanium Oxide)

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".
