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.

Solvent Extraction of Nickel and Zinc from a Waste Phosphate Solution.

PB190028

Publication Date	1970
Personal Author	Powell, H. E.; Smith, L. L.; Cochran, A. A.
Page Count	18
Abstract	The selective recovery of nickel and zinc from a waste phosphate solution by solvent extraction was investigated as part of a broad program to recover valuable metals and compounds from industrial wastes, and to reduce the associated land and water pollution caused by dumping these wastes. The waste, which resulted from the phosphation of automobile bodies, yielded 99 percent of both the nickel and the zinc by extraction with dinonyl naphthalene sulfonic acid (DNSA) and di-2-ethylhexyl phosphoric acid (EHPA), respectively. Dilute sulfuric acid was used to recover the metals and regenerate the solvents. (Author)
