2Department of Earth Science, University of Ghana, Legon-Accra, Ghana Abstract: Arsenic (As) sorption characteristics in decommissioned tailings dam environment at the Obuasi mine, Ghana was studied. The aim was to outline effective remediation strategy for As, hence the objectives were to establish: (1) Arsenic degradation capacity of the decommissioned tailings dam environment and empirical model(s)

Trace elements contamination of soils around gold mine

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. Average concentrations of As, Cu, Pb and Zn in soils

Levels of heavy metals and contamination status of a

In a bid to determine the contamination status of a decommissioned Tailings Storage Facility (TSF 2) from Chirano Gold Mine limited (DXNL), scoop of mine tailings were collected down to a depth of 20 cm from nine sampling sites within a 8100 m2 grid. Concentrations of As (0.7 to 3.3), Pb (1.3 to 2.2), Cr (0.9 to 1.9), Cd (2.0 to 2.6), Cu (5.5 to 6.5), Zn (2.4 to 3.6) and Fe (4.5 to 12) mg/kg were below FAO/WHO

Arsenic (As) sorption characteristics in decommissioned tailings dam at Obuasi mine, Ghana was studied. Results followed reducing mass pattern for both sets of observations. From isotherm applications, equilibrium existed between sorption processes within the media between compliance value (C), ranges of 0.50-0.01 mg/L and time period (t) of 14.5-45.5 months.

CHAPTER VIII CLOSURE AND RECLAMATION Global Tailings Review

filled, decommissioned, stabilised, reclaimed, and deregulated as dams, relinquished and then maintained over the long-term by landowners or regulatory agencies. Where the relinquishment cannot be accomplished, ongoing maintenance will be responsibility of the mine owner. Tailings facilities typically occupy 10 to 40 per cent of the area of a reclaimed mining landscape, with pits and waste
