  • Basic principles of alluvial diamond exploration

    With a few notable exceptions, alluvial diamond mining is the preserve of the individual digger and the smallscale, if more technically sophisticated miner/ digger a private, rather than a corporate operation Corporate interest in alluvial diamond mining began in New South Wales in the late 19th century and in Namibia a few decades later[Introduction]: The principle of alluvial gold mining beneficiation is to maximize the recovery rate of gold and the associated heavy minerals from gangues first and then separate gold from the associated heavy minerals by joint mining solutions such as gravity separation, flotation, amalgamation, magnetic separation, and electrostatic separationAlluvial Gold, Alluvial Gold Mining, Alluvial Mining forA typical example of the major geographic zones of the alluvial gold deposits is the Kibi alluvial gold mining district, which is associated with the KibiWinneba metavolcanics gold belt located at the southeastern end of the Birimian terrain in Ghana (Abouchami et al 1990)Characterisation of alluvial gold exploration data to
