Dec 23, 2008· I have used two techniques for recovering gold from waste. Electroplating in a specialist cell is good at high concentrations but struggles at 20ppm. Ion exchange resins also require dedicated equipment but will reduce the gold content to about 1ppm. In both cases the gold will be contaminated with other metals like nickel and silver if present.
Ion exchange resins, that are semiselective for gold, have been extensively used for gold recovery from cyanide leach processes in the former USSR. Despite forward looking statements by researchers and technology vendors, there have been very few applications in Western plants.

For a single tank and a small operation, ion exchange is one way to recover the gold. Any strong base resin in the chloride form will do this, but you must also find a refiner to complete the recovery. There are also small electrowinners that are made especially for gold. These work best on a stagnant rinse before the final rinse and have the ...
