Ilmenite - an overview ScienceDirect Topics

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.

Direct Carbothermic Reduction of Weathered Ilmenite for ...

2019-3-15  Ilmenite (FeTiO 3) is a titanium-containing mineral abundantly available worldwide, predominantly found in beach sand and placer minerals.The synthetic rutile (TiO 2) is an intermediate chemical derived from ilmenite while producing pure TiO 2.[1,2] The other phase of titanium oxide corresponds to anatase and brookite, generally found as intermediate products.

US4174274A - Separation of rutile from ilmenite - Google ...

Rutile may be separated from ilmenite or ilmenite ores by agitating a mixture of ilmenite and rutile in particle form in an aqueous solution containing a collection agent to which hydrogen peroxide has been added. The slurry in agitated form is treated with air to produce a froth. The ilmenite particles will attach themselves to the air bubbles in the froth and may be skimmed off the surface ...

Rutile - an overview ScienceDirect Topics

2020-6-6  Rutile is often twinned and a complex intergrowth of acicular crystals is known as sagenite.It is often red or brown-red in color which gave rise to the name from the Latin for red, rutilus.Anatase and brookite also have the formula TiO 2 but they have different structures and are said to be polymorphs. Rutile is the commonest form of TiO 2 in nature. . Because it is the high-temperature ...

A Study on the Roasting Process for Efficient Selective ...

2021-3-23  In the past, high-purity TiO 2 and Ti metal were produced from high-grade TiO 2 ores such as rutile using a chlorination-based process. However, the decrease of rutile ore reserves increased its price and resulted in non-steady supply, making the above process not economically viable and necessitating the search for suitable alternatives, e.g., the utilization of relatively abundant low-grade ...
