Prof. Tony Tang
Professor of Practice
AusIMM Perth
Session 11b | Q&A with Session Chair
3:10 PM - 3:25 PMBiography
Tony is a Fellow and Chartered Professional member of the Australasian Institute of Mining and Metallurgy (FAusIMM-CP) and a member of the Australian Institute of Company Directors (MAICD). With over 35 years of experience in the resources sector, Tony has more than 28 years of professional expertise spanning the full life cycle of mineral processing, extraction, refining, and complex chemical projects. His work encompasses concept development, test work, engineering design, construction, commissioning, ramp-up, and steady production operations.
Tony is passionate about developing innovative and sustainable solutions to critical minerals and energy challenges while facilitating collaboration and knowledge transfer between industry and academia. In his role as a professor of practice and technical research leader,
Tony collaborates with academic and research institutions. He recently led cooperative research projects and managed operations at the Cathode Precursor Production Pilot Plant (C4P) at Curtin University. Under his leadership, the project successfully delivered an AUD 15 million Stage 2 program for the Future Battery Industries Cooperative Research Centre (FBICRC), focusing on the development and optimisation of pCAM production using various NCM co-precipitation chemistries for lithium batteries. Additionally,
Tony serves as the chair of the AusIMM Perth Branch, where he advocates for professional development and recognition of excellence within the minerals sector in Western Australia.
