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 ...
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.
Nov 03, 2012· Mass of Titanium from sand mixture? Titanium occurs in the magnetic mineral ilmenite (FeTiO3), which is often found mixed up with sand. The ilmenite can be separated from the sand with magnets.

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, 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, 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.
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 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 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.
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.
Pilot-Scale Demonstration of Ilmenite Processing Technology UMD NRRI iii chloride leaching and solvent extraction system parameters for the ilmenite concentrate. The test program focused on the leach efficiency and extraction efficiency of the target elements; iron and titanium.
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.
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.
May 03, 2018· Ores of titanium Titanium is the ninth-most abundant element in Earth's crust It is present as oxides in most igneous rocks, in sediments derived from them, in living things, and natural bodies of water Titanium-containing minerals or ores are :- 1) Rutile TiO2 (Titanium dioxide) 2) Ilmenite FeTiO3 (Iron titanium oxide) 3) Perovskite CaTiO3 ...
Ilmenite, also known as manaccanite, is a titanium-iron oxide mineral with the idealized formula FeTiO 3.It is a weakly magnetic black or steel-gray solid. From a commercial perspective, ilmenite is the most important ore of titanium. Ilmenite is the main source of titanium dioxide, which is used in paints, printing inks, fabrics, plastics, paper, sunscreen, food and cosmetics.
In experiments, powdered carbon and powdered ilmenite/rutile were evenly mixed and then heated to 1500 degrees Celsius. The end products of this reaction are Oxygen and a high strength Ceramic-metal composite (Cermet) of Iron (Fe) and Titanium Carbide (TiC) which has high chemical stability

The ore, usually an ilmenite, is dissolved in sulphuric acid to form a mixture of sulphates. Any iron is removed from the solution so the colour of the final product is not spoiled. The titanyl sulphate is then hydrolysed in solution to give insoluble, hydrated titanium dioxide.
