The Gold Grinding Process

Gold extraction Wikipedia

Gold extraction refers to the processes required to extract gold from its ores.This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore.. Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold panning and sluicing, resulting in direct recovery of

Ore processing Waihi Gold

Ore processing consists of the following stages: crushing and grinding of the ore; addition of process water (generally decanted from the tailings pond) to form a slurry; addition of lime to the ore, and cyanide solution to the slurry, to leach the gold and silver into solution

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.
