:: Penn State Launches Center for Critical Minerals
Minerals are part of virtually every product manufactured in the modern global economy. New technologies from touch-screen displays to batteries to solar panels and in the medical, energy and defense industries are increasingly reliant on specific critical minerals not widely used a few decades ago.
Many of these critical minerals are imported. They are classified as critical because they have high economic importance, high supply risk, and their absence would have significant consequences on the economic and national security of the United States.
The Center for Critical Minerals will leverage Penn State’s existing faculty, facilities and research strengths in an effort to make the University the go-to resource for critical minerals research and technical support for industry.
Initially launched by the College of Earth and Mineral Sciences, the center will expand to include scientists from across Penn State whose research expertise can be harnessed to address the issues posed by critical mineral exploration, characterization, separation and production.
“We have all the major disciplines and world-class faculty expertise required for this type of work within the college,” said Sarma Pisupati, professor of energy and mineral engineering and director of the center. “We have the skills at Penn State needed to advise industry on locating, mining, characterizing, processing and utilizing critical minerals. We also have strengths in financial analysis.”
There are 35 minerals or mineral material groups that are currently considered critical. The list includes the rare earth element group, a set of 17 metals necessary for devices that people use every day like rechargeable batteries, cellphones and magnets. The U.S. imports nearly 100 percent of its needed rare earth elements, with China producing about 85 percent of the world supply.
“Penn State has a long tradition of meeting industry and government research needs in the minerals field,” said Pete Rozelle, a Penn State alumnus and a retired program manager for the U.S. Department of Energy, who is now serving as an adviser to the college on mineral resources. “From geologic exploration to mineral extraction technologies to techno-economic analyses, the University’s new Center for Critical Minerals offers a comprehensive set of capabilities to support the development of new U.S. sources for these mineral products.”
The new center will build on and expand Penn State’s current research examining cost-effective and environmentally friendly technologies to extract rare earth elements from clay layers associated with coal, coal waste products and acid mine drainage.
“Extracting rare earth elements and other critical minerals from coal sequences and coal waste has the potential to bolster the state’s economy and provide new employment in mining regions,” said Lee Kump, John Leone Dean in the College of Earth and Mineral Sciences. “The opportunities for student engagement in the enterprise means that this initiative touches all aspects of the University’s mission of research, teaching and outreach.”
Pisupati’s team and DOE researchers collaborated to successfully develop an economical way to extract rare earth elements from coal byproducts using an advanced ion exchange method.
In another DOE-funded project, they partnered with Texas Mineral Resources Corp., Inventure Renewables Inc. and K-Technologies to investigate if the process would be feasible on an industrial scale. The overall goal is to find an economical way to extract rare earth elements and critical minerals, such as manganese and cobalt, from coal byproducts.
“Pennsylvania has the resources. Pennsylvania coals and coal-associated products have the highest concentrations of these rare earth elements and critical minerals in the U.S. Penn State is well positioned to play a vital role in helping industrial partners here in the state,” Pisupati said.
The center’s focus is to:
“Coal waste, underclays, metallurgical waste, acid mine drainage and its treatment sludges, and flowback and produced water in the Marcellus basin are additional sources of critical minerals, with low production costs, that could be tied to remediation and restoration efforts,” said Pisupati. “Extracting these materials is a win-win for Pennsylvania.”
