The gold content of the pit samples were 13.13 gt, 3.28 gt and 7.83 gt respectively for Prestea underground ore Pit A, Beta North Oxide ore Pit B and Mampong Transition oreCyanide is the most common lixiviant utilisd to extract gold from primary and secondary raw materials due to its strong complexation with gold and the simplicity of the process. However, environmental and health concerns necessitate alternative methods, such as the recently introduced glycine.Once the gold has been dissolved in the cyanide, and the ore body has been reasonably depleted of its gold, there are two main processes for recovering the gold from the pregnant cyanide solution. One is the Merrill-Crowe zinc precipitation process and the other is the adsorption of the gold
