I have applied fundamental comminution research to design and process improvement on over 60 mines worldwide during 40 years at Mintek, UCT, and the JKMRC. I have communicated my work in over 230 papers, with a focus on application to industry. I collaborate extensively, with close compatriots on 5 continents forming the Global Comminution Collaborative (GCC). My professional objective is to maximise resource utilisation through significantly decreasing the energy and environmental footprint. To this end I provide education into the mining industry, lead the GCC, contribute to University research, and lead three R&D companies.

Joe is Processing Manager at Carrapateena and is responsible for the surface concentrator operations, metallurgy, tailings dam operations and development. Joe also manages the surface Carrapateena Expansion studies scope supporting the growth aspirations of the site. Joe has been a part of Carrapateena management team for 6 years, through construction of the original plant, operational readiness, commissioning, ramp up and now well into debottlenecking. Prior to joining Carrapateena, Joe was Ore Treatment Manager at Newcrest Cadia Valley where he worked for over 5 years delivering significant performance improvements following the Cadia East expansion from 24mtpa to 32mtpa integrating new technology and optimisations across the concentrator flowsheet including delivery the first base metal HydroFloat application globally at Cadia, a technology now under construction at Carrapateena. Previously Joe has been in operational leadership roles at Hillgrove Resources for commissioning at Kanmantoo Copper, and Olympic Dam.

Julian Thomson is currently completing his dual degree of a Bachelor of Chemical engineering and Bachelor of Finance at the University of Queensland. As a recipient of an Ausenco scholarship in 2018, he has been working as an Undergraduate at Ausenco for almost 5 years while completing his studies at university. In the last year he has been working extensively on databasing and analyzing data on coarse particle floatation and regrinding technologies as a combined solution for comminution circuit design and optimization.
