Flotability Improvement of Ilmenite Using Attrition ...

Gravity separation, magnetic separation, and flotation are often combined to the separation of ilmenite and rutile from gangues . For ilmenite, there are many pretreatment methods to improve its flotability, such as the surface dissolution method, oxidation roasting, microwave irradiation, and introducing ions.

Ilmenite/Rutile – Alpha Thermal Process

Ilmenite is often beneficiated to produce synthetic rutile or titaniferous slag [Boateng, 2016]. Although numerous technologies are used to produce synthetic rutile, nearly all are based on either selective leaching or thermal reduction of iron and other impurities in ilmenite.

Ilmenite for pigment and metal production

Rutile is easy to process to titanium metal or TiO2 pigment by the chlorination method while ilmenite is more complicated because of its high iron content. Since the world reserves of titanium are 90% in the form of ilmenite and only 10% in the form of rutile, the treatment of ilmenite is evidently an important question in metallurgy [1,2].

Ilmenite vs Rutile - What's the difference? WikiDiff

ilmenite rutile In contextmineralogylang=en terms the difference between ilmenite and rutile is that ilmenite is (mineralogy) a weakly magnetic dark gray mineral found in metamorphic and igneous rocks; it is a mixed oxide of iron and titanium, fetio 3 while rutile is (mineralogy) the most frequent of the three polymorphs of titanium dioxide, crystalizing in the tetragonal system, ti]][[oxygeno 2 .

A New Process to Upgrade Ilmenite to Synthetic Rutile

The treatment of rutile to produce metallic titanium or TiO2 pigment is relatively simple (Figure 1). Because of its high iron content (30-50%), the treatment of ilmenite is evidently more complex (Barksdale, 1966), (Sibum et al., 1997) and (Habashi, 1993).

Upgrading ilmenite into a high-grade synthetic rutile ...

Ilmenite is currently being mined in annual quantities eight times larger than rutile. In the past 35 years, an increasing percentage of the pigments have been produced via the chloride method, which requires rutile. This has caused the need to produce a synthetic rutile of more than 90% TiO 2 content and large amounts of an 85% TiO 2 slag from ilmenite.
