The Mining Process – Waihi Gold

Ore from both open pit and underground is stockpiled separately at the mill before being fed into a SAG mill with lime, water and steel balls The larger particles from this mill are returned to the SAG mill for more grinding The finer particles receive more grinding in a ball mill, and are size classified to give a final product of 80% < microns

How Is Gold Extracted From Gold Ore? | Sciencing

In all methods of gold ore refining, the ore is usually washed and filtered at the mine, then sent to the mill At the mill, the ore is ground into smaller particles with water, then ground again in a ball mill to further pulverize the ore

How Is Gold Extracted From Gold Ore? | Sciencing

Several processes can then be used to separate the gold from the ore The most common techniques in the United States use cyanide in various ways In one, the ground ore is put into a tank containing a weak cyanide solution and zinc is added The zinc causes a stone reaction which separates the gold from the ore The gold is then removed from the solution with a filter press
