This process removes up to 93 percent of the gold and 70 percent of the silver from the ore. Carbon granules are then added to the solution. The gold attaches to the carbon and is pulled from the solution. We then “strip” the gold from the carbon by washing it with a caustic cyanide solution. The carbon is later recycled. Next, we pump the gold-bearing solution through electro-winning cells, which extract metals
