How Gold Is Refined A Stepbystep Guide Pease Curren

How Gold Is Refined A Stepbystep Guide Pease Curren The result of this process is 99.5 percent pure gold. The final step is to cast the gold into electrodes or anodes and place them in an electrolytic cell. The refiners will then pass an electric current through the cell. At the end of this process, the gold will be 99.99 percent pure. Reclaiming the Mine No goldThe result of this process is 99.5 percent pure gold.
