Mining Gold Ore Concentrate Mercury Amalgamation Barrel Amalgamator Gold and Mercury Distiller Machine
Product Description
The mercury mixing cylinder is a kind of internal mercury mixing equipment widely used in gold concentrator.
It is used to treat the gold bearing heavy sand of placer gold mine and the gravity separation gold concentrate of vein gold mine.
The recovery rate of mixed mercury gold in the mixing cylinder can reach more than 98%, which is an effective internal mixing equipment.
Working Principle
Gold extraction by mercury mixing method is mainly used for the purification of mercury in gravity separation gold concentrate.
The commonly used mercury mixing equipment includes mercury mixing cylinder, mixed mercury grinding machine, mercury plate, etc.
In terms of work efficiency and recovery rate of gold extraction, the mercury mixing cylinder is an ideal choice. The use of the mercury mixing cylinder for the purification of gravity separation gold concentrate is not only high in mercury mixing efficiency, but also can break the contaminated part of the gold particle surface through the role of forced mercury mixing, so that the single substance of gold is exposed and sufficient mercury mixing can be obtained.
According to the relevant data and practice, the recovery rate of the forced mercury mixing cylinder for gold extraction is proved It is higher than 98%, which is one of the relatively high gold extraction efficiency and recovery in the current process.
The mixed mercury grinding machine is a common grinding equipment. Adding mercury into the re grinding machine can also realize the operation of extracting gold by mixing mercury.
However, due to the low efficiency of mercury mixing, large consumption of mercury and low recovery rate of gold, the mixed mercury mill is rarely used for gold extraction. Mercury plate is also a kind of equipment for extracting gold by mercury mixing.
According to the type, it belongs to external mercury mixing equipment. The equipment has simple structure, convenient operation and can operate continuously. However, it can only recover the gold particles with clean surface, and the recovery rate of gold covered by dense film is not good, so it can not play a role of forced mercury mixing.
Therefore, the gold recovered by the equipment is not even much for gold lost.
2. How does the mercury mixing cylinder to purify gold?
Although most of the gold in gravity separation gold concentrate exists in free state, the surface of gold particles is often polluted in different degrees, and some gold exists in the form of connective with other minerals or gangue. When the gravity separation gold concentrate is treated by mercury mixing cylinder, steel ball is often added into the cylinder, and the surface film of gold particles is removed by grinding and the gold particles are separated from the intergrowth. When the heavy sand concentrate containing free gold particles with clean surface is treated, the light mercury mixing cylinder is generally used with less ball loading. Heavy mercury mixing cylinder is often used to treat heavy sand concentrate with high content of intergrowth and serious surface pollution of gold particles.
Application
1. Beautiful appearance, stable and reliable performance.
2. Energy saving and effective, simple and convenient operation.
3. It can reduce the consumption of mercury in the operation of extracting gold and mixing mercury.
4. It is the internal mercury mixing equipment required by gold concentrator

How to use the Automatic Amalgamator ?
1, Each time 30 kg of minerals, the ratio of mercury is 1:10 2, Put the mineral in from above, connect the power and rotate for 20-30 minutes 3, Let it out from the drain hole and mix it with a small amount of water. 4, Finally, water and mercury are twisted out with a fine cloth and reused.
At Last, only need to use the distiller to heat the Gold amalgam as the following pictures
apor mercury steamer should be heating slowly, if heating up too fast, that easy to cause the mercury intense boiling and splashing. Inner temperature in 356ºC, the gasification process begins. When mercury begins a large number of escape after temperature at 400-450ºC, the temperature can be increased to 750 to 800ºC, and then continue to heat 30 minutes under the temperature of distillation to eliminate the residual mercury completely.
