The 2007 Milton E. Wadsworth Award  

Awarded To: Randolph E. Scheffel

"In recognition of his contributions in the field of industrial hydrometallurgy that advance our understanding of leach kinetics and improved recovery of non-ferrous metals."
SME 2008 Milton E. Wadsworth Award lecture: “When it comes to Heap Leaching – all Rates are Relative” --Randolph E. Scheffel Biography of author: Mr. Scheffel received a BS degree in Metallurgical Engineering in 1970 and a MS degree in Hydrometallurgy in 1972, both from the University of Utah. He began his career at Ranchers Exploration and Development Corporation’s Bluebird copper mine, Miami, AZ, in 1972. The Bluebird mine was the world’s first commercial stand-alone copper Heap Leach SX/EW operation. During his 12-year career with Ranchers he was involved in conventional, in-place and in-situ leaching projects, gaining valuable insight to the commercial economics and practical constraints of such endeavors. He has testing, design and operating experience in the Heap Leaching of copper, precious metals, uranium/vanadium, nickel/cobalt and nitrate/iodine ores. Through his consulting practice, he has assisted in the project development and process improvements for many of the Heap Leach projects developed in South America, Australia and Southeast Asia during the last 16 years.
