Three areas of current Bureau of Mines recycling research are summarized in this review article: critical metals recovery from superalloy scrap, utilizing zinc wastes in electrogalvanizing processes, and rapid scrap identification technology. Metals such as cobalt, chromium, and nickel can be recovered from dissolved superalloy scrap if it is made readily leachable by first forming intermetallic compounds with either aluminum or zinc. Zinc- containing furnace dust, currently considered a potential environmental disposal problem, can be used as a replacement for virgin zinc in electrogalvanizing processes. More scrap metal can be effectively recycled if low-cost identification and sorting methods are developed for scrap processors to use. These projects typify the broad spectrum of recycling research undertaken by the Bureau in its efforts to increase mineral recovery from wastes generated throughout the minerals industry.
