The Bureau of Mines studied the chemical recovery of nickel, cobalt, and molybdenum from superalloy scrap. Much of the scrap from the machining of nickel- and cobalt-base superalloys is best utilized by remelting. However, when the scrap is contaminated, consists of mixed grindings, or is of obsolete alloys, chemical processing can convert contained metals to marketable forms. Chemical processing on a laboratory-scale recovered nearly 90-percent of nickel, cobalt, and molybdenum as metallurgical-grade oxides.
