Amalgamation Process of Gold Mineral Processing &Metallurgy

The amalgamation process, which has been widely used in a variety of forms from earliest times, depends upon the wetting and alloying of metallic gold and silver with mercury. Because of its high specific gravity and tendency to be collected by larger masses of liquid mercury or mercurycoated surfaces, this alloy, or amalgam, is readily

The process of amalgamation is the gold processing is a very simple process of mixing between gold and mercury (Hg). Amalgamation Technique performed by mixing rocks containing metallic gold and mercury by using a drum machine tools. Amalgamation of Gold Processing techniques are mostly done by small scale miners and simple.

Mercury is very useful in the processing of gold and silver. This also encouraged to develop mercury ore deposit in the United States after the discovery of gold and silver in California and other western countries in the 1800s. Mercury is widely used in various industrial products and applications after 1900.

In many countries, elemental mercury is used in artisanal and smallscale gold mining. Mercury is mixed with goldcontaining materials, forming a mercurygold amalgam which is then heated, vaporizing the mercury to obtain the gold. This process can be very dangerous and lead to significant mercury exposure and health risks.

Mercury, a dangerous pollutant, is the preferred method employed by smallscale miners for gold recovery. Gold extraction using mercury is comprised of the following four stages: 1) amalgamation, 2) separation of amalgamation, 3) removal of excess mercury, and 4) burning of the remaining amalgam to produce a gold sponge. Mercury can be released

Gold and silver have long been recovered by the amalgamation process, and amalgams of sodium and potassium have been used as reducing agents. Chemical compounds Compounds of mercury have many uses in pharmacology, in chemicalprocess industries, and in agriculture.

Amalgam Definition and Uses  ThoughtCo
Amalgam Definition and Uses ThoughtCo

Amalgams may occur naturally (e.g., arquerite, a natural amalgam of mercury and silver) or may be synthesized. Key uses of amalgams are in dentistry, gold extraction, and chemistry. Amalgamation (the formation of an amalgam) is usually an exothermic process that results in hexagonal or other structural forms.

Mercury is used intensively in gold processing in Manica, Zambezia and Niassa Provinces, where primary gold quartz veins are worked. Manica show levels of contamination around 8.23 g/m3, about 8 times the WHO recommended levels of Hg in humans. The amount of mercury that is used for processing one gram of Au, range between <1 and 15g.
