IMPC 2024: Shaping the Future of Mineral Processing in a Sustainable World



National Harbor, Washington, D.C.—In the midst of the sweeping energy transition, the XXXI International Mineral Processing Congress (IMPC) brought together over 2,000 global delegates from September 29 to October 3, 2024, at the Gaylord National Resort & Convention Center. The five-day event, themed “Meeting the Future Needs of the Energy Transition,” offered a compelling mix of technical sessions, hands-on courses, and innovative discussions, making it a critical touchpoint for an industry in flux.


The congress tackled the dual challenges of sustaining mineral processing innovation while addressing the intensifying demand for materials critical to clean energy technologies. From electric vehicles to renewable infrastructure, the discussions and exhibits at IMPC 2024 reflected not just the present state of the industry but also its rapidly evolving future.


A Scholarly Kickoff: Transformative Short Courses


IMPC 2024 began with three meticulously crafted short courses, each tailored to meet the demands of professionals navigating the complexities of modern mineral processing.


1. Fundamentals of Mineral and Metallurgical Processing


This course offered a rich foundation in mineral processing, making it invaluable for both seasoned professionals and those seeking to refresh their expertise. Dr. Courtney Young of Montana Technological University and Dr. Corby G. Anderson of the Colorado School of Mines led participants through topics such as sampling, comminution, flotation, and environmental management. The course provided a rare opportunity to connect theory with practice, using real-world flowsheets to illuminate the intricacies of material processing.


2. Geometallurgy for Mineral Processing in the Energy Transition


Geometallurgy emerged as a crucial strategy for mining operations grappling with complex and variable ore bodies, particularly those tied to critical energy transition materials. With precision and insight, Dr. Karin Olson Hoal of Cornell University, along with experts from Teck Metals and Blue Coast Research, demonstrated how geometallurgical modeling can mitigate risks, optimize ore recovery, and reduce environmental footprints. Delegates left with a deeper appreciation of how multidisciplinary approaches can align technical, environmental, and social imperatives.


3. Industry Practice in Processing and Refining EV Battery Minerals


With the global push toward electric mobility, the course on EV battery minerals proved to be a standout. Dr. Michael Moats of Missouri University of Science and Technology, alongside co-instructors, offered an in-depth exploration of lithium, cobalt, graphite, and other essential minerals. Delegates gained a comprehensive understanding of the EV battery supply chain—from extraction to recycling—and an insider’s look at emerging technologies shaping the next generation of energy storage.


Each course not only deepened technical knowledge but also fostered collaborative dialogue among professionals eager to tackle the challenges of the energy transition.


A Look Inside: Luck Stone Bull Run Quarry


On October 4, a select group of attendees embarked on a captivating field tour to the Luck Stone Bull Run Quarry in Chantilly, Virginia. Nestled amidst suburban developments, this state-of-the-art facility provided a vivid demonstration of how large-scale aggregate operations can balance cutting-edge technology with environmental stewardship and community engagement.


The tour highlighted the quarry’s automated secondary and tertiary processing systems, showcasing innovations that enhance efficiency while reducing the industry’s carbon footprint. Delegates were particularly intrigued by the site’s role in pioneering autonomous haul truck technology in collaboration with Caterpillar. Although the trucks were not on display, quarry representatives offered insights into the transformative potential of autonomous systems in industrial mining.


In addition to its technical achievements, the site exemplified the importance of a strong social license to operate, given its proximity to residential neighborhoods. One participant reflected, “It’s not just about mining—it’s about mining responsibly. The Luck Stone team showed us what a holistic approach to operations looks like.”


Innovation on Display: The Exhibitor Hall


The heart of IMPC 2024 pulsed within its bustling Exhibitor Hall, where over 200 companies showcased the latest advancements in mineral processing technology. Exhibitors, armed with resources from the congress’s comprehensive Exhibitor Service Kit, created visually striking booths that highlighted innovations in automation, waste management, and recycling.


Beyond the displays, exhibitors leveraged the Marketing Tools provided by the IMPC team, integrating promotional banners and branded content into their outreach strategies. This synergy between planning and execution elevated the professional atmosphere of the hall, making it a must-visit destination for delegates eager to stay ahead of industry trends.


Pioneering Progress for a Changing World


IMPC 2024 was more than a congress; it was a clarion call for innovation, resilience, and sustainability. Against the backdrop of growing global demand for critical materials, the event underscored the indispensable role of mineral processing in shaping a sustainable future.


Delegates left with more than technical insights—they carried with them a renewed sense of purpose. As Dr. Karin Olson Hoal eloquently summarized in her closing remarks, “Our industry stands at the nexus of opportunity and responsibility. The energy transition is not just a challenge; it is our greatest chance to redefine how we engage with the earth and with each other.”


The XXXI IMPC will resonate in the industry’s collective memory as a moment when global leaders came together to tackle the urgent challenges of today while envisioning the possibilities of tomorrow. With the next congress on the horizon, the legacy of IMPC 2024 will continue to inspire a generation of professionals striving to lead the world toward a cleaner, greener future.
