Abstract
Superalloy grinding waste contains substantial quantities of nickel, cobalt, molybdenum, and chromium and for lack of an economical domestic recovery process is being marketed abroad. A process was developed and demonstrated on a laboratory scale for treating this complex waste product to recover the more valuable metals. The recovery process includes scrap preparation, dissolution of metallics in chlorinated acid solution, carbon adsorption, successive solvent extraction separations, and selective chemical precipitations. Nearly 90 percent of the nickel, cobalt, and molybdenum were separately recovered as metallurgical-grade oxides. For a more detailed discussion of the subject see Bureau of Mines report of investigations 7316.
