The Gold Production and Refining Process

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.
