Abstract
The Bureau of Mines has been influential in increasing the recycling of mineral values from various waste materials. Industrial utilization of Bureau research includes cobalt and tungsten carbide recovery from machining tool scrap, regenerating chromic acid from spent electroplating solutions, and resource recovery from municipal solid waste. Current scrap and waste utilization studies are being directed in part toward developing environmentally acceptable and energy-efficient methods of recycling secondary lead, recovering chromium and other critical metals from scrap materials, and developing new uses for nonmetallic scrap. Work is conducted at Bureau research centers located throughout the country as well as at the facilities of private research organizations that have been awarded Bureau contracts. Work in cooperation with the Tanners' Council of America, Inc., has been directed toward developing effective methods for treating leather tanning wastes to prevent environmental degradation while recovering the chromium values for effective recycling. The status of current scrap and waste utilization research is shown in relation to the goals and objectives of the Bureau's mineral resources technology program.
