Assessing bioremediation potential for arsenic released from mine waste rock
Arsenic (As) is a toxic metalloid that is widespread in the environment. Anthropogenic mining activities result in As being released from rock via mining activities in mine tailings, waste rock and process waters. AREVA has a proposed mine site expected to produce up to 6 million tonnes of waste rock containing As. This waste rock needs to be stored appropriately and the release of its As into groundwater must be limited to minimize environmental impacts. The goal of this research project is to assess a bioremediation method for As found in the water and waste rock at relevant mine temperatures.
