Mineral Processing and Recycling
Our research areas:
-
Process engineering in service of the circular economy of raw materials
-
Green chemistry for mineral froth flotation
-
Physical separation technologies for recycling
Our current research activities include:
-
Fundamental understanding of interfacial phenomena in mineral froth flotation
-
Green chemical systems in mineral froth flotation
-
New physical separation operations for battery waste
-
Statistical entropy analysis supported by process simulation as a parameter of materials circularity
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.
