2007 Hall of Fame

William G. Davenport, Professor, Extractive Metallurgy, Department of Mining and Geological Engineering, College of Engineering, the University of Arizona is considered to be among the top two or three academics in the world in the application of thermodynamics and process engineering principles to extractive metallurgical processes. His interest and expertise is in the smelting of copper, nickel, and lead concentrates with the objective of maximization of sulfur dioxide strength, smelting rate, and metal recovery with minimal energy consumption. Southwest U.S.A. smelters produce more sulfuric acid than metal. It is essential, therefore, that these smelter acid plants be optimized in terms of energy minimization, gas and liquid flow minimization, corrosion, environmental contamination, and acid purity.

While an American citizen today, Professor Davenport was born in the gold mining community of Bralorne, British Columbia, Canada. He received his first two degrees in metallurgical engineering at the University of British Columbia, finishing with a Ph.D. from the Royal School of Mines, University of London and a D.I.C. from Imperial College.

He began his teaching career at McGill University in Montreal in 1964 where he rose to full professor and Associate Dean of the Faculty of Engineering. He came to the University of Arizona in 1981 as Professor and Head of the Metallurgical Engineering Department.

Professor Davenport is best known from his textbook, Extractive Metallurgy of Copper, which is now in its 4th printing in both English and Spanish. This is a comprehensive text detailing the mineral processing as well as the pyrometallurgical and hydrometallurgical processes commonly used for the extraction of copper from ores. It includes operating data on selected plants around the world. In addition he has published a number of other books: The Iron Blast Furnace; Theory and Practice, which was published in English, Russian, Chinese, Japanese, and Spanish; Flash Smelting - Analysis, Control and Optimization, which is now in its 2nd printing; and Sulfuric Acid Manufacture-Analysis, Control and Optimization. He is currently writing Extraction of Nickel, Cobalt, and Platinum Group Metals.

He has numerous scholarly publications resulting from his research in the fields of flash smelting, leaching and solvent extraction, electrowinning, and electrorefining. He holds a number of Canadian and U. S. patents in the plating and purification of metals.

Professor Davenport has been recognized by a number of the international professional societies in his field and has received a number of professional awards including being named as the AIME Extractive Metallurgy Lecturer in 1983 and receiving the AIME Mineral Industry Educator of the Year Award in 2003. He was made a Fellow of the Canadian Institute of Mining, Metallurgy and Petroleum in 1991.

Professor Davenport has an extensive consulting practice that has included Union Carbide Corporation, Duval Corporation, Phelps Dodge Corporation, Codelco-Chile, and ENAMI-Chile and has been an advisor to the World Bank. He currently works with EHP Consulting here in Tucson.

Harry Parker is widely known and respected as a foremost authority and expert in the field of resource modeling and geostatistics. He has emphasized preparation of resource models that reflect both local geological controls on grade and orebody geometry as well as the degree of selectivity implicit in the mining method.

Harry received his BSc in. Geology with departmental honors from Stanford University in 1967, followed by his AM in Geology from Harvard University in 1969. Between 1965 and 1975 he worked as an Exploration and Staff Geologist for the Hanna Mining Company, focusing on exploration for nickel laterites, nickel-copper-cobalt sulfide deposits, volcanogenic massive sulfide deposits, and Mississippi Valley-type zinc deposits. While working for Hanna, he obtained his MSc in Statistics in 1974 and his PhD in Geology in 1975 from Stanford University.

From 1975 through 1989, Harry served as a Mining Geologist and Geostatistician for Flour Corporation. During his tenure at Flour he was involved in a wide variety of consulting assignments on six continents that focused on coal, uranium, copper and gold deposits and the developmment of state-of-the art geostatistical and mine planning software. He was a member of first U.S. mining delegation to China in 1977.

From 1989 to the present, Harry has been Technical Director of AMEC and its predecessor firms (MRDI, H.A Simons and Agra), and has been actively involved in the resource modeling of copper, molybdenum, gold, zinc, iron, silver, nickel, and PGE deposits worldwide. He has trained operations staff and implemented computer-based orebody and resource modeling systems on the Zambian Copperbelt in Africa, an has led or advised teams responsible for providing Qualified Person's reports in connection with the change in ownership of major mining assets around the world.

Hary is a Professional Geologist (California, Arizona), a Chartered Professional Geologist and Fellow of the Australasian Institution of Mining and Metallurgy (AusIMM), a Fellow of the Society of Economic Geologists (SEG), an Honorary Life Memeber of the Geostatistical Association of Australasia, and a member of the Phi Beta Kappa. He currently serves as the Chairman of the Registered Member Admissions Committe of the Society for Mining, Metallurgy and Exploration (SME), as Co-chairman of the SME Resources and Reserves Committee, and is a U.S. representative on the International Committee for Resources and Reserves Reporting. He is the author of numerous published technical papers. Harry currently resides in Incline Village, Nevada, with his wife Susan.

Thomas Lovering was born on May 12, 1896 in St. Paul Minnesota. His career is marked by broad experience in ores that begin with his training as a Naval Aviator in the First World War followed by a return to school where he received an E.M. degree from the Minnesota School of Mines in 1923, and an M.S. and Ph.D. in economic geology in 1926 from the University of Minnesota. His graduate studies at Minnesota were influenced by Frank Grout and John Gruner who stimulated life-long interests in the hydrothermal processes that form ores. His subsequent employment cycled between teaching and government work. After a year of teaching at the University of Arizona, he joined the U.S.G.S. in 1925 to conduct studies of mining districts in the Colorado Front Range under the supervision of B.S. Butler where he refined his interpretations of hydrothermal alteration from studies in the Colorado Tungsten districts. He returned to teaching, at the University of Michigan in 1934 but maintained work with the U.S.G.S, ultimately publishing professional papers on the tungsten, precious, and base metal districts. He rejoined the Survey, taking leave from Michigan, during the Second World War to assist the Strategic Metals Program.

His wartime work led to concern about domestic metal resources and a focus on methods of discovery of hidden ore bodies. He studied the alteration of the deeply concealed ore bodies at Tintic, Utah as a full-time Survey employee and the work at Tintic resulted in a maps and interpretations of alteration that facilitated discoveries at East Tintic.

He was appointed chief of the U.S.G.S. section of Geochemical Exploration and retired as a senior research scientist in the Geologic Division in 1966 at age 70. During retirement, he was a research Professor at the University of Arizona, and lectured at the University of Texas and the University of Utah.

Tom Lovering was a member of the National Academy of Science, a recipient of the Distinguished Service Metal of the U.S. Department of the Interior, the Penrose Gold Medal of the Society of Economic Geologists, the D.C. Jackling Award of the American Institute of Mining, and Metallurgical Engineers, and the Achievement Award of the University of Minnesota. Tom Lovering was a conscientious teacher and scientist who brought to colleagues and students the personal and professional habits of dedicated work, high ethical standards, and intellectual honesty. His major contributions to the knowledge of ores, regions, and exploration are outstanding.

Herman Ehrenberg led an extraordinary life of adventure representative of the colorful characters that founded this country and also made significant contributions to the foundations of Arizona’s mining legacy. Ehrenberg was born in Prussia and as a teenager traveled to New York. In 1835, he enlisted with the New Orleans Greys on behalf of what would become the Texas Republic. After fighting in the Battle of Bexar, he served under Col. James W. Fannin at the Battle of Coleto where he was taken prisoner and subsequently survived the Goliad Massacre by escaping in the confusion of the mass killing and swimming the San Antonio River.

After another capture by Mexican troops, Ehrenberg escaped a second time and after the Texas Revolution worked as a merchant between New Orleans and various Texas ports. During the period 1842-1844, he returned to Germany for health reasons and during this time wrote his memoir of the Texas Revolution, taught English, and learned mining engineering and surveying with the help of his brother who was enrolled in the mining school at Eisleben.

Ehrenberg appears to have returned to the United States in early 1844, traveled to Oregon and then on to the Sandwich Islands (Hawaii) where he published a map of the streets of Honolulu in 1845. Ehrenberg returned to the mainland in 1847 working on a merchant ship and traveled to Spanish California during the Mexican-American War where he worked out of La Paz, Baja California. It was during this time that he was cited for bravery in assisting the American military in rescuing several American sailors held by Mexican guerillas. He then went north and stayed on in California for the gold rush where he found little success. He did, however, met Charles Poston in San Francisco in 1854, and it was with Poston’s Sonora Exploring and Mining Company, headquartered in Tubac during 1854-1861, that Ehrenberg made his first contributions to Arizona mining. He worked as a surveyor and mining engineer at the Salado and Cerro Colorado Mines, and prospected the area from the Santa Cruz Valley westward to Ajo and otherwise assisted Poston in his efforts to establish Arizona as a separate territory. As a part of this effort, Ehrenberg drafted the first map of the area of the Gadsden Purchase that resulted in his being hailed as "one of the greatest surveyors and map makers ever to visit the Western United States."

During 1862 Ehrenberg (having evacuated Arizona to California during the Civil War) returned from California to join the rush to the Colorado River gold placers where he was responsible for the organization of the La Paz and Castle Dome Mining Districts. He took an active part in the development of the Picacho Mine near La Paz and the Harcuvar Copper Mines. In 1866 he was appointed probate judge for Yuma County and also apparently served as an Indian Agent for the Mohave Tribe. He was killed by unknown assailants near Dos Palmas, California, while returning from a trip to San Bernardino in 1866.
