Mercury amalgamation method is based (aqueous silver) extracted from natural pulp of the gold particles. When mercury is in contact with gold-containing materials, it can selectively wet gold particles, which is the theoretical basis for amalgamation. The mercury paste is separated from the slurry, and the remaining mercury is extracted from the liquid (paste) mercury paste, and the obtained solid amalgam is sent to the distillation, and the black sponge gold remains in the distillation tank. . Once the mercury vapor has condensed in the condenser, it can be returned for reuse. This is the basic process of amalgamation.
The process by which the metal is wetted by mercury and then the mercury diffuses into the interior of the metal to form a mercury paste is called amalgamation. Due to the presence of oxide film on the metal surface and the difference in thickness and density, the possibility of metal amalgamation is also different. Compared with other base metals, gold oxidizes at the slowest rate, and the resulting oxide film is the thinnest, making it the easiest to be amalgamated. Silver and platinum are prone to amalgamation between the majority of base metals. However, individual base metals, such as copper , are more likely to be amalgamated than platinum.
