Grant has over 10 years’ mineral processing engineering experience in design, optimisation, operation, research and development. He is a passionate mineral processing engineer that enjoys implementing process improvements by applying fundamental understanding to industrial problems.
Grant has been involved in successful site-based industry research over the past ten years covering five continents and eight commodities. He completed a Bachelor of Engineering (Metallurgy and Chemical) at UQ in 2007 and a Doctorate in Philosophy at the JKMRC in 2012.
At Ausenco, Grant co-ordinates the comminution group including the assessment of new technologies and flowsheets. He also provides input at the front-end of engineering design projects, consults into operations, and assesses the application of enhanced process technologies such as coarse particle flotation and bulk ore sorting.
Award
In 2017 he was awarded the Minerals Engineering International Young Person of the Year at the MEI Comminution ’18 Conference in Cape Town. Grant played a principal role in the development of the internationally supported comminution energy curve tool which is widely used by industry for energy benchmarking and the optimisation of comminution circuits.
