The Mining Process – Waihi Gold

Mining – open pit and underground. ... 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 ...

Processing, smelting and refining gold World Gold

2021-2-26  The two gold refining methods most commonly employed to derive pure gold are: the Miller process and the Wohlwill process. The Miller process uses gaseous chlorine to extract impurities when gold is at melting point; impurities separate into a layer on the surface of the molten purified gold.

3 Working Principle of Cyanide Leaching of Gold -

Cyanide leaching of gold is a common step used in the separation between gold concentrate and gangue minerals. Generally, the common gold extraction processes mainly include gravity separation, flotation, magnetic separation and electric separation, and the low grade gold concentrate obtained by the above gold extraction processes can be further processed using cyanidation method.
