Gold Extraction
Amalgamation is a process by penyelaputan gold particles and form mercury amalgam (Au – Hg).
Amalgam is still the gold extraction process the most simple and inexpensive, but effective process
for gold ore, high-yield and has a coarse grain size (> 74 microns) and in the form
pure gold that is free (free native gold).
The process of amalgamation is a process of physical chemistry, amalgamnya when heated, it will decompose to
elements of mercury and gold bullion. Amalgam can be broken down by heating in a
retort, the water will evaporate and raksanya can be obtained back from the condensation of the mercury vapor.
While the Au-Ag remained behind in the retort as a metal.
