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.

Solubility and Activity of Aluminum Chloride in Aqueous Hydrochloric Acid Solutions.

PB80123128

Publication Date	1979
Personal Author	Brown, R. R.; Daut, G. E.; Mrazek, R. V.; Gokcen, N. A.
Page Count	26
Abstract	The solubility and the activity of aluminum chloride hexahydrate, AlCl3.6H2O, in aqueous solutions were determined as a part of the Bureau of Mines, U.S. Department of the Interior, research to improve mineral processing technology for recovering alumina from low-grade domestic resources. The results were shown to be useful in leaching nonbauxitic ores for extraction of alumina by changing the solubilities of component salts upon addition of HCl. Simultaneous solubilities of AlCl3, FeCl3, KCl, and NaCl in solutions of HCl-H2O were also determined and their effects on the purity of AlCl3.6H2O crystallized from mixed salt solutions are briefly discussed.
