  • How Gold Is Mined Gold Mining Process World Gold

    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 Waihi Gold

    A slurry of ground ore, water and a weak cyanide solution is fed into large steel leach tanks where the gold and silver are dissolved. Following this leaching process the slurry passes through six adsorption tanks containing carbon granules which adsorb the gold and silver. This process removes 93% of the gold and 70% of the silver.

    Gold cyanidation Wikipedia

    John Stewart MacArthur developed the cyanide process for gold extraction in 1887. The expansion of gold mining in the Rand of South Africa began to slow down in the 1880s, as the new deposits being found tended to pyritic ore. The gold could not be extracted from this compound with any of the then available stone processes or technologies.
