Gregory Dipple, Professor, Earth, Ocean and Atmospheric Sciences
Greg Dipple is a Professor in the Department of Earth, Ocean and Atmospheric Sciences at the University of British Columbia and a long-time member of the Mineral Deposit Research Unit. He studies mineral-fluid interactions in environments ranging from the Earth’s surface to the deep crust using tools from geochemistry and mineralogy. Specific studies grounded in field work and experimental geochemistry are interpreted in the framework of reactive transport modelling to understand the processes of, controls on, and implications for mineral-fluid reaction in hydrothermal systems, mineralization, and carbon sequestration, including in mine tailings.
Dirk van Zyl, Professor, Norman B. Keevil Institute of Mining Engineering
Dirk has more than 30 years experience in research, teaching and consulting in tailings and mined earth structures. During that period he was a faculty member for 13 years at four Universities in the US and Canada. For the last 10 years much of his attention has been focused on mining and sustainable development. He has been involved internationally in many mining projects. These projects covered the whole mining life cycle, from exploration to closure and post-closure, in a large range of climatic and geographic environments. His present research is in the area of the contributions that mining makes to sustainable development as well as the application of life cycle assessment to mined earth structures.
