The impact of artisanal gold mining, ore processing and
At the entables, the ore is crushed, then finely ground using small ball mills, known as cocos, to separate free gold and gold-bearing pyrite from the rock gangue.Denser gold flakes and sulphides are concentrated by gravimetry using cyclones and Wilfley tables (Fig. 2c). Gold is recovered from the concentrate by physical processes and by mercury amalgamation.
