NTIS: PB 190 028 :14 pages
The selective recovery of nickel and zinc from a waste phosphate solution by solvent extraction was investigated by the Bureau of Mines as part of a broad program to recovery 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 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.
