The amalgam ball from a Chilean trapiche clean-up contains one ounce of gold. It is about 30 percent gold and 70 percent mercury. The economic benefits from gold, in the millions of ounces, recovered by trapiche amalgamation in Chile are now being partially, and painfully, offset by the recognition of environmental damage.

The principle of gold extraction by using mercury (amalgamation method) is mainly that after the mercury is added to the slurry, the surface of the gold particles is wetted by mercury, and then the mercury diffuses into the interior of the gold particles, causing a chemical reaction. Au+2Hg=AuHg2. Finally, the solid of Au3 Hg will form.
