Mining and Ore Processing

Mercury that is not processed or claimed during mining and ore processing can make its way into the environment if the mining waste is not stored properly. Mercury is also extensively used in the gold mining process as an amalgam for separating gold from ore.

Hard Rock Mining Gold and Silver Ore and processing it

In most gold ores, the final process to extract the tiniest gold particles is the use of cyanide to dissolve the gold. Cyanide, in the presence of oxygen actually dissolves both gold and silver. It is both efficient and inexpensive, so it is widely used in precious metal ore processing.

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.
