Daniel Cowan Jackling

Daniel Cowan Jackling was a world renowned mining and metallurgical engineer, eminent business executive, benefactor, and loyal friend of Utah and its people. Guided by an inspired vision, he applied and developed processes for the beneficiation of low grade porphyritic ores and originated copper mining methods revolutionary in character and on a scale never before attempted, resulting in the worldwide production of new wealth in the form of precious metals, copper, and other essential minerals in quantities never before attained in the history of man. He assembled the now world famed Utah Copper Mine in nearby Bingham Canyon and through his research implemented and developed that property from a body of supposedly worthless porphyry rock into the world’s greatest copper producer of all time. His civic services and leadership in major economic and political projects left lasting imprints on the growth and development of the state of Utah. Copper production at the Bingham Canyon Mine was a major factor in Utah’s industrial development and prosperity, and in 59 years of operations 1,354,772,000 tons of waste were removed, 926,065,000 tons of ore were mined, and 16,873,244,000 pounds of copper were produced, with expenditures totaling $2,767,625,000, including $839,558,000 in taxes, $658,745,000 for payrolls, and $1,269,322,000 in supplies and services.
