WebThe Mercury Problem in Artisanal Gold Mining. Mercury-based artisanal and small-scale gold mining (ASGM) causes more mercury pollution than any other human activity. 1 In this practice, mercury metal is used to extract gold from ore as a stable amalgam. The amalgam is then heated to evaporate the mercury and isolate the gold. WebThe ore goes for preliminary screening, followed by stream sampling, which is a process that uses a hammer sampler. A semi-autogenous mill (SAG) or ball mill is then used to grind and crush the gold ore to a smaller particle size. After this milling, the stream is fed to a trommel screen and next, a cyclone circuit.
