How Mercury & Gold Amalgamation Works

 · This would be equivalent to about 10 parts of mercury to 1 part of gold. The barrel was rotated for twenty minutes and then discharged into a settler, and the suspended amalgam caught on copper plates. The mercury was supposed to be reduced by the iron thus: HgCl2 + Fe = FeCl2 + Hg, and the metallic mercury thus freed amalgamated with the gold.
