Abstract :
Washington Award Announced for 1940 The Washington Award “in recognition of pre-eminent service in advancing human progress” has been conferred for 1940 upon Daniel Cowan Jackling, “for pioneering in large-scale mining and treatment of low-grade copper ores, releasing vast resources from formerly worthless deposits.” Doctor Jackling, who is president of the Utah Copper Company, San Francisco, Calif., and a past president of the American Institute of Mining and Metallurgical Engineers, demonstrated the possibility of profitable exploitation of low-grade porphyry orebodies and was active in the formation of the Utah company to develop such ores. Among improvements in mining operations for which he was responsible have been the use of electric shovels for digging, steel construction in mill buildings, and three-phase alternating current in connection with hydroelectric developments. He received the John Fritz Medal in 1933.
