A new shine to gold: Reducing health hazards of artisanal and small
Artisanal and small-scale gold miners pour mercury into ground ore where it merges with gold flecks to form an amalgam— essentially a ball— of mercury and gold. They then burn this ball to evaporate the mercury so what is left is often a tiny porous nugget of gold. Miners working on this evaporation are consistently exposed to mercury ...
