Recovery of TiO2 from ilmenite-type ore using an ...

Sep 18, 1979· An improved process is described for producing titanium dioxide from ilmenite-type ore. The ore is digested with aqueous hydrogen fluoride, the resulting liquid mixture treated with a water-soluble oxidizing agent, and the ferric iron impurities, in the resulting digestion solution, at a pH between about 1.0 and 6.0, are extracted out with a mono-or dialkyl, or mono- or di-(alkylphenyl ...

australia ilmenite resources

In consequence, our deposit is a HM-mineralised soil profile that requires unique but simple extraction and processing requirements. As a direct analogy, our 'ore' probably constitutes a similar original source of ilmenite prior to the extensive (100's of millions of years) erosion, transport and reworking as found in the classic sand systems.

extraction of titanium - chemguide

As far as I can see there is only one UK-based Exam Board that wants the extraction of titanium, and that is AQA. They only want the conditions and equations for the reactions involved, and that is all you will find on this page together with a few comments related to method used.

titanium | Properties, Uses, & Facts | Britannica

Titanium, chemical element, a silvery gray metal of Group 4 (IVb) of the periodic table. It is a lightweight, high-strength, low-corrosion structural metal and is used in alloy form for parts in high-speed aircraft. Titanium is widely distributed and constitutes 0.44 percent of the Earth's crust.

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 - Essential Chemical Industry

Manufacture of titanium dioxide. There are two main processes, the Sulfate Process and the Chloride Process (Table 1) which use the two principal ores, ilmenite and rutile, respectively. Ilmenite contains 45-60% TiO 2 and rutile contains up to 99% TiO 2. The ores are mined worldwide but most production is in Australia and South Africa.

Ilmenite : Wikis (The Full Wiki)

Ilmenite most often contains appreciable quantities of magnesium and manganese and the full chemical formula can be expressed as (Fe,Mg,Mn,Ti)O 3. Ilmenite forms a solid solution with geikielite (MgTiO 3) and pyrophanite (MnTiO 3) which are magnesian and manganiferous end-members of …

Titanium extraction

Titanium extraction The process used to extract titanium is called the Kroll process and is named after William J. Kroll, who invented the method in the 1930s. It is slow and has at least two steps. First the titanium oxide ore is reacted with chlorine to make titanium chloride. 1.

Solvent extraction of titanium from the simulated ilmenite ...

The extraction of Ti from the simulated ilmenite sulfuric acid leachate was investigated using TRPO-kerosene extraction system. The effects of stirring rate, contact time, TRPO concentration, phase ratio, and temperature were examined. Optimized extraction conditions were found to be: 25% (v/v) TRPO in kerosene, O/A 4:1, and temperature 30 °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.

Kroll process - Wikipedia

The Kroll process is a pyrometallurgical industrial process used to produce metallic titanium.It was invented in 1940 by William J. Kroll in Luxembourg.After moving to the United States, Kroll further developed the method for the production of zirconium.The Kroll process replaced the Hunter process for almost all commercial production.
