The Gold Production and Refining Process

Using chemical substitution called the electrolytic process, the gold is precipitated from the solution and it is finally in its pure form. This pure gold is then melted into bars called "dore" bars that contain up to 90% gold. These bars are then sent to precious metal refiners for further refining until the bars of gold are up to 99.9% pure gold.
