Mineral Processing and Recycling

Among the major issues facing our modern, civilized world is an ever-increasing demand of raw materials. For that reason, the aim of our group is to find technological solutions to address the current needs related to the production of inorganic raw materials, whether from primary or secondary sources.

The Research Group for Mineral Processing and Recycling is led by Prof. Rodrigo Serna. Our approach is to study the underlying phenomena responsible of the performance of mineral processing operations. Of particular interest is the study of the interfacial phenomena occurring during mineral enrichment, in order to gain a practical understanding on the correlation between adsorptive or surface chemical reactions and the macroscopic performance of the operations. Through the understanding of the phenomena involved, it may be possible to propose novel chemical systems that could further improve the efficiency of currently used enrichment operations, or even propose new processing methods altogether. The research group also counts with expertise in computational fluid dynamics with which alternative processing systems or new designs of mechanical components can be tested.

Our current research projects deal with the exploration of green chemicals for flotation and the quality and potential cross-contamination in water circuits. Our research group is also responsible for the courses related to mineral processing and recycling, including fundamentals, unit operations and plant design.
