The true cost of producing an ounce of gold | Provident

Another process involves ground ore being passed over plates which are coated with mercury. The gold and the mercury form an amalgam, leading to the name of the process, amalgamation. Once the amalgam has formed, it is heated until the mercury gas is boiled off, leaving the gold. The mercury gas is highly toxic and must be handled carefully.
