Abstract
The Bureau of Mines, U.S. Department of the Interior, conducted laboratory-scale research on scrapped ni-cd batteries to devise a pyrometallurgical method for recovering cadmium as part of its efforts to conserve mineral resources through increased recycling. The method employs reduction and/or decomposition and distillation of the metallic cadmium at atmospheric pressure and 900 deg c. Cadmium content of the nickel product has been consistently less than 0.05 pct. Optimum conditions for maximum cadmium removal are 900 deg c for 120 minutes, using 2.5 pct carbon as a reductant.
