Gold mercury amalgam barrel is the traditional gold refining machine; it's been widely used to mix the mercury and gold concentrate from shaking table, sluice box or gold concentrator, in order to get the pure gold from black sand. 

Our automatic mercury amalgamator is newly designed, use motor to drive the machine, instead of manual. use the stepper motor for easier operation; use stainless iron barrel to get a long service life and saving the mercury; reasonable structure make this machine neat and clean

1. High recovery ratio more than 98%, The mercury lose is low.

2. Total process automation, steady recovery performance

3. Center discharge design for fast, secure removal

4. Environmentally (requires no release mercury)

5. Low water and electricity requirements

6. Low production costs, durable wear parts, minimal maintenance requirements

7. Compact design requiring less space, easy merged into the existing mining processing

8. Quick payback on investment, typically less than half year

9. Completely closed operation

Amalgam barrel is used to recover the gold from ore concentrate, heavy sand and various ores.

Although most of the gold in gold concentrate is in free form, the surfaces of gold grains are usually polluted to a greater or less extent, and some gold exists with other minerals or vein rocks in adherent form. . When gold concentrate is processed with amalgamation cylinder, steel balls are usually added to the cylinder for grinding operation to remove the film on gold grain surfaces and separate the gold grains from adherent bodies.

When the heavy sand ore concentrate of free gold grains with clear surfaces is treated, we usually use light-duty amalgamation cylinder with extremely small quantity of steel balls. . When processing the heavy sand ore concentrate with high adherent body content and serious gold grain surface contamination, we usually use heavy duty amalgamation cylinder, for which 1-2 kg of steel balls need to be loaded for 1kg of heavy sand ore concentrate. . The loading quantity of concentrate and steel balls of amalgamation cylinder is related to material grain size and gold content.

During non-alkaline medium amalgamation, heavy sand ore concentrate may produce magnetic mercury amalgam due to the interfusion of Fe substances. . Hence, internal amalgamation is usually operated in alkaline mediums. The quantity of lime is 2%-4% of loading capacity, and water quantity is usually 30%-40% of loading capacity; alternatively, the usual grinding concentration can also be used.

Amalgam barrel is mostly used to extracting gold particles. It’s widely used in gold mining project and small family gold mining
