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. Most of the ilmenite mined worldwide is used to manufacture titanium dioxide, TiO 2, an important pigment, whiting, and polishing abrasive. ADVERTISEMENT.

Abstract. Several methods used to extract iron from ilmenite concentrate to increase TiO 2 content of ilmenite concentrates such as Benelite, Ishihara, Murso, Austpac, and Becher methods. Benelite method uses HCl for leaching of reduced iron from ilmenite.
The conventional methods used for ilmenite ore processing include gravity separation, high-intensity magnetic separation, and electrostatic separation or a combination of them (Fang et al., 2019). In some situations, ilmenite is freely disseminated in the gangues and cannot be effectively separated from the associated gangue minerals using the ...
In the processing of ilmenite, it is always a difficult problem to recover the fine size. In mineral processing, the flotation method can only realize the recovery of granular ilmenite less than 0.02mm to a certain extent, but there will be a lot of quartz and other veins in the fine ore powder after flotation, which seriously affects the ...

World demand and production of diamond both for gem and industrial purposes has increased nearly five-fold during the past 25 years. Improved mining and recovery methods together with the discovery and development of new fields has enabled mining ...
Ilmenite (FeTiO3) is black and opaque when fresh, ... Mineral Sands Processing Various methods which include magnetic, gravity and electrostatic separation as well as chemical processes, are then used to separate the sands into individual mineral species. The ore is put through a screening plant which breaks it down into individual grains.
Early Method of Processing Ilmenite In the early method of TiO 2 pigment man - ufacture from ilmenite the ore was treated with concentrated H 2 SO 4 at 110–120°C to form ferrous and titanyl ...
Possibilities For All Flotation Treatment of Titanium Ore. To develop a flowsheet for separation of high grade titanium-rutile from ilmenite, that will meet market requirements. Rutile has a SG of 4.2, hardness 6.0 to 6.5 and is non-magnetic; while ilmenite has a SG of 4.5 to 5.0, hardness of 5.0 to 6.0, and is weakly magnetic.
The invention relates to a method for producing titanium oxide-containing slag and pig iron from ilmenite. The method is characterized in that it comprises the steps: a) pre-reducing ilmenite in the presence of reductant in a prereduction reactor to metallize at least part of iron in the ilmenite; b) optionally removing unreacted reductant and gangue from the pre-reduced ilmenite; and c ...
Ilmenite is brittle and dense. Due to the physical and chemical properties of mineral surface, it is not easy to recover coarse ilmenite by flotation process. However, fine or fine ilmenite has good floatability and can be recovered by flotation method. 1. Flotation Process 1) Conventional flotation method. In the conventional flotation process ...

A new method of altered ilmenite processing has been studied. In this method, sulfuric acid is used as the reaction medium of the process, and fluoride ions are activators of the dissolving process of the rutile part of the ore raw material. The regression model of the sulfate–fluoride leaching process was developed and analyzed by using the response surface method of 23 matrix.

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].

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 and/or metallic iron. The resulting product is then leached with a dilute inorganic acid to solubilize the reduced iron values.
