Trace element contaminants associated with historic gold

Trace element contaminants associated with historic gold

As a historic gold mining area, the City of Benoni has numerous water bodies close to major tailings dams and mine dumps. Here we assess spatial patterns in the sediment geochemistry of five dams and four natural pans within a 5-km radius of the core mining area to determine the degree of contamination7 by mining-associated pollutants.

The environmental impact of gold mine tailings footprints

The environmental impact of gold mine tailings footprints

Gold mining in South Africa resulted in vast volumes of tailings, which have been deposited in impoundments. Poor management of most of the tailings dams resulted in the escape of seepage, adversely affecting soils and water quality. Some tailings dams have been partially or completely reclaimed leaving contaminated footprints. These zones pose a serious threat to the underlying …

Gold tailings as a source of waterborne uranium

Gold tailings as a source of waterborne uranium

In addition to this most gold tailings produced before 1952 were never leached for U (a few old slimes dams, however, were later reworked to recover U), and therefore also contain U in elevated concentrations as found in the mined ore.
