"I was drawn to this field because of its crucial role in sustainability"

Meet the professor who transforms mining challenges into sustainable solutions. Saeed Chehreh Chelgani develops smarter mineral processing and recycling methods – from AI-driven flotation to battery recycling – shaping the future of resource efficiency.

Could you tell me a little about yourself and your research?

— I’m a professor of mineral processing and the Director of the Swedish School of Mines at Luleå University of Technology (ranked within the top 2% of scientists worldwide). My work primarily focuses on mineral processing, particularly flotation separation, AI modeling, surface chemistry, and developing materials for both primary and secondary mineral processing. My research spans from fundamental studies on particle–bubble interactions to applied projects in battery recycling, green flotation mechanisms, chemicals, and new reagent development. Currently, I’m involved in projects on lithium-ion battery recycling, phosphate flotation in collaboration with LKAB, and AI modeling of industrial units.

What made you choose this field of research?

— Mineral processing is a fascinating blend of chemistry, physics, and engineering, all applied to solving real-world resource challenges. I was drawn to this field because of its crucial role in sustainability—how we efficiently process raw and secondary materials, minimize waste, and develop innovative ways to recycle and recover valuable elements. The complexity of flotation beneficiation and surface chemistry, in particular, keeps me engaged; even after years of research, there are always new challenges and discoveries to be made.

Why did you decide to conduct your research at Luleå University of Technology?

— Luleå University of Technology is a leading institution in mining and mineral processing, with strong industry connections, excellent research facilities, and a collaborative environment. The university has a long tradition of working closely with companies like LKAB, Boliden, and other key players in the mining and recycling sectors. It also supports interdisciplinary work, allowing me to collaborate with experts in chemistry, AI, and materials science. The strong industrial ties and cutting-edge research opportunities made the university an ideal place to pursue my work.

How long have you been in Luleå, and what are the benefits of doing your research here?

— I’ve been in Luleå for over six years, and it has proven to be an excellent place for research and education. One of the most significant advantages is the direct access to Sweden’s mining and metallurgy industry, which allows for applied research with real impact. The university also fosters a highly collaborative environment where different research groups—such as mineral processing, waste science, and process metallurgy—can efficiently work together. Beyond research, Luleå offers a good quality of life, a close-knit academic community, and access to nature, making it a great place to live and work.

Would you recommend Luleå University of Technology to other researchers, and if so, why?

— Yes. The university offers strong industry connections, state-of-the-art research facilities, and a collaborative environment that supports both fundamental and applied research. It is highly international, welcoming researchers from around the world, and provides excellent opportunities for interdisciplinary projects. If you are interested in mining, mineral processing, materials science, or sustainable resource utilization, Luleå University of Technology is an excellent place to conduct research.
