    Mar 12, 2018 History of Mining in Ghana. There is evidence of gold extraction activities in Ghana as far back as the 7th and 8th centuries A.D., as gold deposits attracted Arab traders into the country.7 These activities were strategically located along rivers where sediments believed to contain deposits of gold were washed constantly to separate the gold grains.8 This was a

    Mercury contamination by Au mining activities is also of great concern in Ghana because mercury is used effectively to extract gold in artisanal gold mining. The optimal Hg to Au ratio is about 1:1 (v/v) but most gold washers in Ghana commonly add greater quantities (Hg: Au = 4:1) to ensure that all available gold is amalgamated (Babut et al

    The main gold prospects in Ghana occur at Obuasi, Prestea, Bogoso and Tarkwa (Smedley, 1996). Large-scale mining in the Bogoso-Prestea region is conducted as both deep-pit and surface mining. Cyanidation is the most common technique in the region and is used for treatment of non-sulphidic palaeoplacer ore (Akosa et al., 2002; Kortatsi, 2004)
