Whereas mining generates much-needed sources to energy the world financial system, the trade is searching for methods to scale back its environmental footprint. To handle challenges in mining, akin to soil and water air pollution and water utilization, inventors from the College of Arizona College of Engineering have joined forces with an skilled mining trade entrepreneur to launch the startup Auxilium Technology Group. The Tucson-based firm has licensed UArizona innovations that supply sustainable and holistic options that tackle rising considerations about mining’s influence on the atmosphere and local weather change.
Beneath the management of Auxilium CEO Abraham Jalbout, the corporate will develop the innovations, which make ore leaching processes extra environment friendly and fewer poisonous, contribute to water conservation, and cut back power consumption.
“The place others see waste, we see alternative,” Jalbout stated. “We’re bringing collectively these applied sciences from the totally different folks on the group, and we’re placing them collectively in a circuit to create a holistic strategy to tailings administration, which makes a really distinctive worth proposition within the tailings world.”

Tech Launch Arizona, the UArizona workplace that commercializes innovations stemming from analysis, has labored intently with the group in launching the brand new ventures and has licensed three patent-pending applied sciences to Auxilium; extra licenses for extra innovations are in dialogue. This kind of entrepreneurial collaboration provides a pathway for college researchers seeking to enhance the influence of their analysis and advance the trade, whilst they continue to be dedicated to educating the subsequent era of mining professionals.
TLA Senior Licensing Supervisor Bob Sleeper and Mentor-in-Residence Steven Wood labored with the inventors and Jalbout to launch the corporate and license the applied sciences.
“As a spine trade of the U.S. financial system, mining corporations are hungry for these sorts of options,” stated Sleeper, who works with college inventors to refine and shield mental property and to match innovations with licensee corporations. “There’s lot of public strain to wash up present mining programs, not construct new ones, and that’s what makes these applied sciences thrilling. The concept we will work smarter and make present mines cleaner to function is a worldwide concern.”
Jaeheon Lee, an affiliate professor of mining and geological engineering, contributed one of many licensed applied sciences – a leaching course of that makes use of the organosulfur compound thiourea somewhat than the extra poisonous factor cyanide to extract gold from ore. The method he developed can attain as much as 98% effectivity of extraction, leading to larger profitability and decrease toxicity.
“Generally you’ve gold in your copper or copper in your gold, and it should be despatched to a processing plant. Moderately than get 100% of the dear metals, they could obtain 35 to 85%,” he defined.
Affiliate professor Moe Momayez, interim head of the Division of Mining and Geological Engineering and David and Edith Lowell Chair in Mining and Geological Engineering, contributed two different licensed applied sciences.
Storing mine tailings – a typical trade apply – requires pumping waterborne refuse materials into human-made ponds the place it’s saved and separated. Momayez invented a system of floating, interlocking panels that cowl tailings ponds to scale back evaporation and enhance the quantity of water out there for reuse. The system additionally will be outfitted with photo voltaic panels to generate electrical energy.
He additionally invented a spray-on thermal insulating geofoam made with mine tailings. When sprayed on the partitions in sizzling underground mines, the geofoam gives a layer of insulation that stops warmth from radiating from the rock into the working areas, considerably lowering the price of cooling the air. The group additionally foresees a possibility to leverage this know-how to learn the development trade.
The Auxilium Expertise Group management group additionally contains Dominic Gervasio, affiliate professor of chemical and environmental engineering at UArizona, who brings experience in making use of chemistry to the processing of ore.
“Our final aim is to achieve zero waste,” Momayez stated. “Mining is a really water and energy-intensive trade. We’re excited to supply options that extract valuables from mining effluents and cut back mine waste – essentially the most seen footprint of the mining trade.”
Auxilium’s rising know-how portfolio displays its aim of making sustainable options for points affecting right this moment’s mining trade. Constructing on a long-standing relationship with the School of Engineering, Jalbout continues to work intently with UArizona inventors and Tech Launch Arizona to determine new applied sciences that shall be helpful for the corporate and contribute to higher sustainability for the trade.
