manganese crushed fines

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. The leach cycle is normally from 20 to 30 days. When the leaching cycle is complete, a new crushed ore is piled.
