With more than 18 years of work and research experience in mining and mineral processing engineering, Dr Bueno has in-depth knowledge of designing and optimising comminution circuits and geometallurgy. He completed a PhD at the University of Queensland, specialising in multi-component autogenous and semi-autogenous grinding. He has conducted extensive comminution circuit surveys and pilot plant campaigns in Australia and internationally. As a senior process engineer for Ausenco, he has been involved in technical and engineering studies related to most key mining commodities. More recently, as a senior researcher and lecturer at the University of Oulu, he developed the Geopyörä breakage test with financial support from Business Finland.

Malcolm has applied fundamental comminution research to design and process improvement on over 70 mines worldwide during 35 years at Mintek, UCT, and then as Professor of comminution at the JKMRC in Australia. His work is published in over 200 papers and has been presented in as many conferences worldwide. Malcolm collaborates extensively, with close compatriots on 5 continents forming the Global Comminution Collaborative (GCC) – providing an expert research and consulting base covering the full comminution process chain. Malcolm provides on-site experiential training and site reviews to empower mine staff to upgrade the productivity and their skills. This is supplemented with formal training workshops on liner design, comminution and Advanced Mine to Mill. Malcolm’s research vision is of integrated total process simulation as a tool for innovation – linking geology, mining, energy and size reduction, gangue rejection and recovery into flexible process design and process optimisation.
