A process for treating ilmenite to obtain a beneficiated product having a relatively high titanium dioxide content. Particulate ilmenite is first heated in the presence of a reducing agent to reduce the iron compounds in the ilmenite to ferrous oxide andor metallic iron. The resulting product is then leached with a dilute inorganic acid to solubilize the reduced iron values.

the solids in suspension. After rusting, the beneficiated ilmenite and hydrated iron oxide were separated by dilution and decantation, washing repeatedly, until the solid product is free from iron oxide. The solid product after acetone rinsing was subsequently dried. 3.3.3 Rutilation of beneficiated ilmenite
Malaysian ilmenite from amang or tin mining waste is well known for its physical and chemical complexity, making it difficult to be treated conventionally. With knowledge of ilmenite is rich in titania and iron, extractive efforts were made in order to segregate and recover the components of ilmenite, with major interest being the removal and retrieval of titanium.
Ilmenite is a lustrous black to brownish titanium ore, essentially FeTiO3. Iron-black, heavy, metallic oxide mineral, composed of iron and titanium oxide FeTiO, which is the major source of titanium. Thus ilmenite has enough titanium in their composition to be considered titanium ore when found in large enough deposits.
The beneficiated ilmenite product derived from the low grade ores by reduction and ferric chloride leaching, although its titanium dioxide content is only about 80 wt , is not of sufficient purity to be commercially comparable to rutile. However it nevertheless finds many industrial applications particularly as a flux component in the ...
NRRI runs a pilot plant to optimize beneficiated Longnose concentrate. BHP established a pilot plant at the NRRI lab at Coleraine, Minnesota. BHPs goal was to make synthetic rutile using an oxidation-reduction step on ilmenite concentrate followed by an HCl leach.
Jan 01, 2015 Reoxidation of beneficiated ilmenite plays a major role in rendering the product amenable to acid attack and removal of residual iron.
