The Carleton University Department of Geography and Environmental Studies is delighted to have Dr. Richard T. Amos, Assistant Professor in the Institute of Environmental Science and the Department of Earth Science present, “Managing mine waste in Canada’s North” as part of the Founders Seminars Series.

Abstract:
The recovery of resources such as gold and diamonds requires excavation of substantial amounts of rock that are permanently stored on the mine site in large piles. These waste-rock piles, when exposed to air and water, can leach acidic water with high concentrations of metals and other contaminants. Managing this waste in an environmentally responsible and socially acceptable manner is a major challenge for the mining industry and represents a significant financial liability. Research at the Diavik Diamond Mine in the Northwest Territories and the Detour Gold Mine in Northern Ontario has investigated the mechanisms of gas, water and heat transport through experimental and operational waste-rock piles in an effort to understand the rate and extent of geochemical reactions leading to acidic leachate. The results of the research will be used to better predict leach water quality and manage mine waste.

Biography:
­­­­His research involves the study of contaminant hydrogeology and specifically water quality issues related to the resource extraction industry; including the study of mine wastes and the effects of petroleum spills on groundwater.
