National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Separation of Columbium, Tantalum, Titanium, and Zirconium from Titanium Chlorination Residues.

PB211935

Publication Date	1972
Personal Author	Merrill, C. C.; Couch, D. E.
Page Count	13
Abstract	Columbium, tantalum, titanium, and zirconium are present in solid waste products generated by chlorination of rutile used for production of titanium tetrachloride (TiCl4). The columbium and tantalum were separated from titanium and zirconium by liquid-liquid extraction techniques using a secondary amine. Salts of these elements are in a leach liquor produced by water leaching of mineral waste from the chlorination of rutile. This waste, produced at the rate of approximately 50,000 tons annually, is about 40 weight-percent water soluble. Leach liquors, separated by filtration, were further separated into a solid fraction and a liquid fraction by pressure hydrolysis. The solid fraction containing Cb, Ta, Ti, and Zr was dissolved in HCl-HF and used as a feed solution. Cb and Ta were removed from the organic extractant with 1N HCl. (Author)
