How Gold Is Mined Gold Mining Process World Gold Council

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 as how to extract and process the ore efficiently, safely and responsibly.

The Mining Process - OceanaGold

Once full of gold the carbon travels to a gold desorption column designed to wash the gold out of the carbon. When this process is complete, all that is left is eluate containing hot water, gold solution, cyanide, and caustic soda. The eluate is transported to the gold room and electroplated onto cathodes wrapped in steel wool.

Gold extraction - QueensMineDesignWiki

Once the gold ore has been removed from underground and brought to surface, an entirely new challenge begins in separating the gold from the waste material. The separation process is particularly difficult due to the usually low quantity of gold relative to waste. Common gold grades are in the same magnitude as about 5 g/t, or 0.000005% gold content by weight. This means that upgrading the ...
