Mercury-free, small-scale artisanal gold mining in Mozambique
The overwhelming majority of artisanal and small-scale gold miners utilize mercury to separate gold from the unwanted gangue materials (Telmer and Veiga, 2009). Miners use rudimentary tools to mine and process ore, adding elemental mercury to amalgamate fine gold particles after grinding the ore in a ball mill and concentrating by panning.
