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 well ...

Gold extraction - Wikipedia

Gold processing - Gold processing - Mining and concentrating: The nature of the ore deposit determines the mining and mineral processing techniques applied. Oxide ore deposits are frequently of such low grade (e.g., 3 to 10 parts per million) that extensive mineral processing cannot economically be justified. In this case they are merely shattered by explosives and then piled into heaps for ...
