This report describes a process for recovering chromium and other metals from superalloy scrap. Part I contains the results of laboratory-scale experiments that were conducted to test a complex flowsheet utilizing a wide range of extractive metallurgical operations. The basis for the process is the formation of a sulfide matte in which chromium is concentrated as a discrete chromium sulfide phase. Mineral processing and hydrometallurgical procedures are used to separate chromium sulfide from the other matte constituents. Part II encompasses a preliminary engineering design of a pilot plant capable of treating 100 pounds of superalloy scrap per hour. Also included is an economic analysis of the operation of the pilot plant.
