Amalgamator
Amalgamation cylinder, as a type of internal amalgamating equipment, which is widely used in gold processing plant. It is used to process heavy sand containing gold from alluvial soil mine and gold concentrate of vein gold mine, presenting a recovery rate of higher than 98%.

Description & Technical Data
Working Principle
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 inter-fusion 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.

Frequently Asked Questions
Q: What is the smallest gold particle size this concentrator can recover?
A: It can recover gold particles as fine as 0.004mm, with a recovery rate of approximately 97% for this size fraction.
Q: How often do I need to clean out the concentrate?
A: The cleaning-up cycle is typically 1–4 hours for vein gold and 2–6 hours for placer gold, depending on the grade of your ore.
Q: Does this machine require chemicals?
A: No. The centrifugal concentrator uses only water and electricity. It is a completely physical separation process with zero chemical pollution.
Q: Can I use this concentrator for tailings re-processing?
A: Yes. It is widely used to recover fine gold from old tailings, grinding circuit discharges, and flotation concentrates where fine gold has not been fully captured.
