abstract = "The usage of remediated mine sites is common around the World. Such is the ubiquity of these sites that local residents may often be unaware of their proximity to a former mine site.

As a result, different countries will also vary their methods of remediation to accommodate these different factors. Many countries now have adopted far more sustainable methods of remediation in keeping with GSR principles. Previously China relied primarily on mechanical excavation in order to remediate its former mining areas due to the low cost of the operation. Now however, the country has made more investment into more sustainable methods, including the commonly used technique of combining multiple methods to accommodate the different characteristics of a mine area.

This area has been found to contain highly elevated levels of arsenic in the sub-soil due to the previous use of the site as an As processing facility. There are plumes of contamination in three major spots, upstream and downstream of the calciner in the NE and around the stack in the centre west of the site. This investigation has recommended the more highly contaminated area downstream of the calciner should undergo encapsulation to prevent mobilisation of the concentrated As and the remaining contamination should undergo mechanical excavation and reuse as aggregate material in construction. This investigation then goes on to recommend the subsequent reuse of the Roseworthy site for environmental monitoring undertaken by the nearby Camborne School of Mines (CSM) as an academic asset.
