Argex develops new titanium dioxide process for ilmenite
In the wilds of Quebec Canada a junior mining company has pioneered a new process for the extraction of titanium dioxide (TiO 2) from ilmenite that differs significantly from the existing chloride and sulphate processes. This new process was developed by Canada Titanium Ltd (CTL) which was purchased in October 2011 by Argex Mining Inc.
Titanium Dioxide Production by Hydrochloric Acid Leaching Of ...
of choice in the present article is used economically for production of titanium dioxide. The last compound is used in many fields of application such as catalysts  cosmetics  solar batteries  and ceramic materials . The extraction of titania from ilmenite (ore or mineral) was the subject of numerous studies [6 8 3 11 13].
Extraction Of Titanium Form Ilmenite Stone Equation
Reduction of titanium by aluminum from ilmenite and rutile proceeds via the formation of intermediate monoxide TiO TiO x which as basic oxide is able to form titanium aluminate. This decreases the activity of TiO and makes titanium recovery more difficult. Ver Precio extraction of titanium dioxide from ilmenite ore Mineral.

The extraction of titania from ilmenite (ore or mineral) was the subject of numerous studies [6 8 3 11 13]. Most of these studies were concerned with the extraction of titania from ilmenite by H2SO4 and HCl whereas few ones were directed to extraction of titania by interaction with alkaline reagents [9 1 7].

Argex develops new titanium dioxide process for ilmenite
Canada’s Argex Mining is pioneering a new process that can extract problematic elements and still produce high quality TiO2 In the wilds of Quebec Canada a junior mining company has pioneered a new process for the extraction of titanium dioxide (TiO 2) from ilmenite that differs significantly from the existing chloride and sulphate processes.
Kinetics and Reaction Mechanism of Soda Ash Roasting of ...
Ilmenite by virtue of being rich in iron often has small concentrations of impurities such as Mn3O4 Al2O3 CaO Cr2O3 and MgO. Removal of iron and other impurities is essential for the production of pigment grade TiO2. An investigation of the removal of iron was undertaken by roasting the mineral ilmenite with soda ash in air above 873 K. A ternary phase was identified which played an ...

The major material for titanium extraction is ... on reaction mechanism of ilmenite ore smelting for titanium production. ... recovery of titanium dioxide from ilmenite ores by direct leaching ...
Solvent extraction of titanium from the simulated ilmenite ...
An alternative approach to addressing the wastes discharge as well as obtaining high quality of titanium dioxide is to separate titanium and iron from the ilmenite sulfuric acid leachate prior to hydrolysis (Duyvesteyn et al. 2002). Solvent extraction is one of the most effective technologies for solution purification.
extraction of titanium - chemguide
Titanium extraction. The overall process. Titanium is extracted from its ore rutile - TiO 2. It is first converted into titanium(IV) chloride which is then reduced to titanium using either magnesium or sodium. Conversion of TiO 2 into TiCl 4. The ore rutile (impure titanium(IV) oxide) is heated with chlorine and coke at a temperature of about 1000°C.
Ilmenite – the primary source of titanium extraction by ...
Ilmenite – the primary source of titanium extraction by chlorine process. Ilmenite is the most important ore of titanium mining with the chemical formula FE-TI-O3 (iron titanium and oxygen) named for its place of discovery at Ilmen Lake in the Ilmen Mountains Miask in the southern portion of the Ural Mountains of Russia.
Titanium dioxide - Wikipedia
Titanium dioxide also known as titanium(IV) oxide or titania / t aɪ ˈ t eɪ n i ə / is the naturally occurring oxide of titanium chemical formula TiO 2. When used as a pigment it is called titanium white Pigment White 6 (PW6) or CI 77891. Generally it is sourced from ilmenite rutile and anatase.
Titanium Dioxide (TiO2) Production and Manufacturing Process
TiO2 is produced from either ilmenite rutile or titanium slag. Titanium pigment is extracted by using either sulphuric acid (sulphate process) or chlorine (chloride route). The sulphate process employs simpler technology than the chloride route and can use lower grade cheaper ores. However it generally has higher production costs and with acid treatment is more expensive to build than a chloride plant.
Development of Extraction Method and Characterization of TiO2 ...
2extraction was conducted using sulphate method by reacting milled iron sand with sulfuric acid at high temperatures (>110°C) for ± 30 minutes. Titanium extract was then heated at a temperature of 90°C to precipitate TiO 2. The precipitate was obtained by centrifugation at 10000 rpm for 10 minutes to solidify the precipitate and separate
