Advances in Titanium Extraction Metallurgy SpringerLink

20/12/2013  Titanium is an attractive metal for use in both aerospace and commercial applications. However, because of the high cost of extraction and processing, titanium use has been less than anticipated. The present paper addresses the question of reducing the cost of titanium production either by replacing the present Hunter or Kroll extraction processes by a more cost-effective method, or in

Recent Progress in Titanium Extraction and Recycling

titanium product excluding the gaseous elements was 99.9 pct. However, the titanium metal was brittle and not cold-workable because it was heavily contaminated with oxygen. After improving the impurity control methods during the reduction process, Hunter obtained cold-workable and high-purity titanium. The Hunter process was put to practical use in the

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.

Hunter process - Wikipedia

It was invented in 1910 by Matthew A. Hunter, a chemist born in New Zealand who worked in the United States. The process involves reducing titanium tetrachloride (TiCl 4) with sodium (Na) in a batch reactor with an inert atmosphere at a temperature of 1,000°C. Dilute hydrochloric acid is then used to leach the salt from the product.

Extraction of Titanium - QS Study

Extraction of Titanium. According to abundance in earth’s crust, it is in ninth position (0.6%). About 7-10% Titanium dioxide (TiO 2) is found in the stone of Moon’s surface; which was collected by the space craft Apollo- 11. Titanium is extracted from its ore, rutile – TiO 2. It is first converted into titanium chloride, which is then reduced to titanium using either magnesium or sodium. The ore rutile (impure titanium

Titanium processing - Extraction and refining Britannica

Titanium processing - Titanium processing - Extraction and refining: The production of titanium metal accounts for only 5 percent of annual titanium mineral consumption; the rest goes to the titanium pigment industry. Pigments are produced using either a sulfate process or a more environmentally acceptable carbo-chlorination process (described below) that converts TiO2 into TiCl4. The latter process also supplies the TiCl4 necessary for the production of titanium

Hunter process - Wikipedia

The Hunter process was the first industrial process to produce pure ductile metallic titanium.It was invented in 1910 by Matthew A. Hunter, a chemist born in New Zealand who worked in the United States. The process involves reducing titanium tetrachloride (TiCl 4) with sodium (Na) in a batch reactor with an inert atmosphere at a temperature of 1,000°C.

Thermodynamics of Titanium - Home

It is impressive that it took nearly 120 years before titanium extraction from its ore was successful. The individual that was finally successful in extracting titanium from its ore is a gentleman by the name of M.A. Hunter. His basic process involved mixing TiO2 with chlorine and coke. The result was TiCl4 which was then reduced by sodium (Na). Although the Hunter process (4) was successful ...
