The ores sometimes contain as little as 5/100 of an ounce of gold per ton of rock. 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.

7 Gold & Silver Gold has played a prominent role in world economic and political events. Most of the cyanide leaching is the chief method use. In this technique, sodium or appliion rates generally between 0.5 and 1.0 pound of sodium cyanide per ton of solution.
In the process of heap leaching, pool leaching and CIP production of oxidized gold ore, the process is as same as the process of using sodium cyanide. The pregnant solution and the lean solution in production can be reused, and the best material in pregnant solution gold leaching is activated carbon.
