Feb 29, 2016 Cyanide solution percolates through the heap leaching the gold and silver and is collected on the pregnant solution pad. The ore is crushed to a size that will give good liberation of gold minerals. In most operations with this crushing stage, the ore is crushed until two-three inch. A finer size can be considered if the ore needs fine liberation.

When the Stamp Mill is in operation you can hear it a mile away. In the earlier years the Stamp Mills ran 24 hours a day. So if you lived near one of the mines you didnt get much sleep. When the Stamp Mill was being used commercially the two tables in front of the batter boxes would be covered with mercury to catch the gold.
The faster the mill speed, the greater the wear on the rods and liners. So, the general rule of thumb for rod mills is to operate no faster than the speed that will obtain the desired product size. The operation speed of rod mills is generally determined by the Peripheral Speed of the Inside of the mill. Generally, rod mills operate between 280 ...
