Resources, Conservation and Recycling 123:117-134(2017)

The potential for resource recovery and/or remediation of metalliferous mine wastes in southwest England and Wales was based on an assessment of the physicochemical composition of several key metalliferous legacy mine waste piles and an analysis of their co-location with cultural, geological, and ecological designations. The majority of the 14 sites studied contain relatively high concentrations of metals and metalloids, including Cu, Zn, As, Pb, Ag and Sn, many of which exceed ecological and human health risk guideline concentrations. The economic value of metals in the waste potentially could be used to offset rehabilitation costs. About 70% are co-located with at least one cultural, geological, and ecological designation. This co-location with designations related to their mining activities—due either to historical significance, rare species assemblages, or geological characteristics—demonstrates the need to consider the cultural and environmental impacts of rehabilitation and/or resource recovery on such sites. http://orca.cf.ac.uk/94469/
