DR. MALCOLM POWELL
Malcolm has applied fundamental comminution research to design and process improvement on over 60 mines worldwide during 30 years at Mintek, UCT, and the JKMRC. His work is published in over 200 papers. Malcolm collaborates extensively, with close compatriots on 5 continents forming the Global Comminution Collaborative. 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.
Recent work on advancing the mine to mill concept has focussed on turning this knowledge into an applied process tool for medium to short-term planning and daily operation through implementing blast design, ore tracking and dynamic model-informed milling control. The work at Barrick Cortez mine demonstrates some of this approach.
