(2) Desorption: Desorbing the gold on the resin into the solution with a desorbent. A mercury-gold amalgam then is formed because gold will dissolve in the mercury while other impurities will not. The mixture of gold and mercury is then heated to a temperature that will vaporize the mercury, leaving behind the gold.
