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.

Ore processing – Waihi Gold

The ball mill is very similar to the SAG mill, except it has a larger proportion of steel balls to assist in the grinding process. Following grinding in the ball mill, the material is returned via the sump (8) to the secondary hydrocyclone (9) for resizing. The trash screen (10) removes wood from the old mine workings that may have found its ...
