Wet pan mill is a popular gold and silver ore grinding machine in Africa and South America countries, because of its low investment, easy use and maintenance, and quick cost recovery.
The most common way is to put mercury in the wet pan mill, and mix the gold particle with the mercury, which is called Amalgamation. Then the mixture of gold and mercury can be put into crucible for high temperature heating. During this process, the mercury is evaporated and pure gold is left in the crucible.
