How Gold Is Mined | Gold Mining Process | World Gold Council
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 well1 Mining – open pit and underground To define the ore from the waste rock, samples are taken and assayed Assay results are used to mark out areas of ore and waste rock, which are mined separatelyThe Mining Process – Waihi Gold
