This study investigated the issue of tailings dams as a potential source of trace elements contamination in soils at the Obuasi gold mine in Ghana. Soil samples taken from depths of up to 12 cm and within a radius of 400 m from the tailings dams (active and decommissioned), were analysed for As, Cu, Pb and Zn using atomic absorption spectrometry.

Dams are normally constructed from the coarse (sandy) fraction of tailings, which makes them relatively cheap to build, but potentially inherently weak and susceptible to seepage. Unlike a conventional water reservoir, where the dam is built as a complete structure in one go, tailings dams are built in stages using an initial starter dyke followed by a series of raises as the capacity of the ...

The tailings impoundment dams were upgraded and reinforced or in some cases reconstructed, to minimise seepages and provide a minimum 1 m depth of water cover. With the exception of Stanleigh mine, which was closed in 1996 and rehabilitated during the late-1990s, the water covered Tailings Management Areas (TMAs) at other sites have been in operation for a period of six to nine years.
