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.

Producing Chlorination-Grade Feedstock from Domestic Ilmenite - Laboratory and Pilot Plant Studies.

PB86171113

Publication Date	1986
Personal Author	Elger, G. W.; Wright, J. B.; Tress, J. E.; Bell, H. E.; Jordan, R. R.
Page Count	32
Abstract	The Bureau of Mines investigated the conversion, at both laboratory and pilot plant scale, of a low-grade ilmenite to chlorination-grade feedstock that could substitute for imported rutile used to produce titanium tetrachloride. The concentrate was derived from the Tahawus, NY, lode deposit of ilmenite-magnetite in rock that contains anorthosite and gabbro. Charges of the ilmenite concentrate, containing 46.6 wt pct TiO2 blended with soda ash, were carbothermically reduced in an electric arc furnace, which separated most of the iron and left a high-titanium slag. However, the slag contained Ca, Mg, and Mn constituents that rendered the material unsuitable for continuous chlorination by causing plugging problems. After being ground and pelletized, the slag was reacted with SO2 and air at 700 to 900 C, which selectively converted the harmful impurities to soluble compounds that were removed in a subsequent water or dilute HCl leach.
