About Us
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 from the solution using an electrical current. After gold has been ...
