  • How Gold Is Mined Gold Mining Process World Gold

    the lifecycle of a gold mine. people in hard hats working underground is what often comes to mind when thinking about how gold is mined. yet mining the ore is just one stage in a long and complex gold mining process. long before any gold can be extracted, significant exploration and development needs to take place, both to determine, as accurately as possible, the size of the deposit as well 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 gold mine lasts forever. No one can
