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. This talk will introduce you to research at the Diavik Diamond Mine in the Northwest Territories and the Detour Gold Mine in Northern Ontario that aims to better predict leach water quality and manage mine waste.
