At time Mercury was used to extract metallic gold from gold ore. The ore was crushed to powder, and washed over a copper sheet covered in mercury. The gold would combine with the mercury, and be recovered by distilling the mercury. This was very dangerous due to the poisonous nature of mercury- and it only captured about 15% of the gold. It is no longer used in gold mining.
