The purpose of a gold mill, at least a simple one, is to crush and grind rock fine enough to release small particles of gold. After liberating the gold from the rock or gangue, it is then run through a gravity separation step, which will concentrate most of the gold and wash off the lighter waste rock. Step 1.

The 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.
The cyanidation process in small-scale gold mining. Amalgamation, which is the final phase of gold extraction, also needs technological improvement. At present, mercury is the most common substance used to separate gold particles from the soil, particularly when the gold is fine as in alluvial ore.
To better understand the processes involved in small scale gold mining and gold processing and to evaluate the losses of metals including the losses of the anthropogenically introduced Hg, we ...
