Amalgamation Process of Gold
The use of direct amalgamation following stamps or primary mills and the use of barrel amalgamation for treating jig and corduroy concentrates. Precipitation of gold and silver on zinc dust or on zinc shavings is fully treated, from the clarification and de-aeration of cyanide solutions to the cleanup and melting of the bullion. The use of aluminum dust, sodium sulphide, and charcoal as

Gold amalgamation process in mz
AMALGAMATION IN MZ Whole ore amalgamation is used for primary gold. The ratio of 4-15:1 Hg:Au is estimated in whole ore amalgamation. In some countries you can find ratios of 50:1 (Indonesia) The process of amalgamation itself frees up to 60% of mercury into the atmosphere. For fine stone alluvial gold the Hg is added after pre concentration
Amalgamation: Using Mercury to capture fine gold, retort
Occasionally, the amalgamation process does not collect as much gold as anticipated. This type of result usually occurs when the formation of amalgam is inhibited due to poor contact between the gold and the mercury. This happens most commonly when the gold is very fine or when it is tarnished by a surface or film. Also, the feed material may be contaminated with any grease, oil, or any other
