Nelson has over 30 years’ experience in civil and geotechnical engineering working in research, construction, engineering design, and project management on several mining and industrial projects in Africa, North America and Australia. He holds BSc (Hons) degree from Ghana, M.Eng. and PhD in geotechnical engineering from Memorial University, Canada.

Nelson’s industry practice in Australia over the past 23 years includes several years with large consulting engineering companies where he played leading roles in geotechnical and tailings facilities design, construction, and mine closure. He was principal geotechnical engineer at GHD until 2004. Since then, he has worked for large mining companies including 5 years with BHP Billiton Worsley Alumina and then Newmont Mining Ltd where he spent 3 years as regional manager for mine closure projects in charge of Asia Pacific Region.

He joined Karara Mining in 2012 as manager in charge of capital works program. Nelson is currently general manager projects and asset compliance and the registered manager for the Karara Magnetite Processing Operation. A key aspect of Nelson’s accountabilities in Karara has been the technical development and management of Karara’s Large Scale Tailings Filtration and Dry Stack facility (currently the largest of such operation in the world) and for the past 8 years, he has conducted research/investigations and overseen its design and operational development.

Professor Andy Fourie
Professor of Civil, Environmental & Mining Engineering
The University of Western Australia

Andy is a Professor in the Department of Civil, Environmental and Mining Engineering at The University of Western Australia in Perth. He has a Bachelor and Master degree from the University of the Witwatersrand in South Africa, and a PhD from the Imperial College, University of London. He has worked at the University of Queensland, the University of the Witwatersrand and has been a visiting professor at the University of Alberta, the Catholic University of Valparaiso in Chile and the University of Colorado in Boulder. His research is in the field of mitigating the impact of mining and municipal solid waste disposal. Outcomes from his research have been incorporated in changes to environmental legislation in South Africa. He contributed to a series of guidelines for managing mine tailings in Australia, as well as developing a document for the International Atomic Energy Association on barrier systems for retaining uranium mining waste. Andy has been involved in many industry-focussed projects with current projects including an evaluation of tailings storage facilities monitoring technologies managed by AMIRA and funded by eight mining companies, Future Tails aimed at training, research and education to improve tailings management funded by BHP and Rio Tinto and evaluating potential static liquefaction of tailings to prevent failures, funded by six mining companies as well as the Australian Research Council. Andy is also currently a member of five international tailings review boards.

Dr Gordon McPhail

Gordon has worked as a consulting engineer to the mining industry, specialising in the geotechnical and environmental aspects of mine waste management for 42 years and has participated in projects in Africa, Australia, and North and South America.

Dr David Reid
Research Fellow
The University of Western Australia

David is a tailings engineer with 14 years’ experience in the design, laboratory testing, investigation, and analysis of tailings and tailings storage facilities. He is primarily involved in laboratory and in situ characterisation of tailings with respect to strength, consolidation, and liquefaction. David completed a PhD from The University of Western Australia, which involved studying the properties of polymer-treated tailings and the use of centrifuges to perform consolidation testing. In November 2017, David joined UWA’s School of Civil, Environmental, and Mining Engineering for an ARC Linkage project focused on static liquefaction of tailings.
