The two gold refining methods most commonly employed to derive pure gold are: the Miller process and the Wohlwill process. The Miller process uses gaseous chlorine to extract impurities when gold is at melting point; impurities separate into a layer on the surface of the molten purified gold.
By much small-scale mining equipment and processing beneficiation practice, people discovered that gravity is the most efficient and the most stable method to grade small-scale gold mine. The small-scale gold mine in different regions by the above processes can .
Clean Mining is working to transform gold production worldwide through new processing technology that eliminates cyanide as a means of extracting the precious yellow metal. The solution represents transformational change achieved through the commercialisation of new, environmentally-conscious ore processing that sets a new 'gold standard'.
Artisanal Gold Mining Description. Artisanal and small-scale mining refers to mining activities that use rudimentary methods to extract and process minerals and metals on a small scale. Artisanal miners also frequently use toxic materials in their attempts to recover metals and gems.

Mwamba is creating an economically and environmentally sustainable future for the artisanal and small scale gold mining sector. Current processing techniques rely on the use of mercury which is both inefficient and toxic.
Gold deposits along the general gold path can be small or large, depending upon the size of the gold trap. The most important type of gold trap in river mining is called the "pay-streak". Pay-streaks always form along the gold path where the river's flow slows down on a large scale during a major flood storm.
Artisanal and small scale gold mining is, globally, the largest source of anthropogenic (man-made), mercury emissions. Arsenic and cyanide contamination are other consequences of illegal gold mining.
The Artisanal Gold Council releases the first version of its field health education flip charts "Health in Artisanal and Small-Scale Gold Mining." This is an educational material accompanies with "Health Issues in Artisanal and Small Scale Gold Mining: Training for Health Professionals."
In many countries, elemental mercury is used in artisanal and small-scale gold mining. Mercury is mixed with gold-containing materials, forming a mercury-gold amalgam which is then heated, vaporizing the mercury to obtain the gold. This process can be very dangerous and lead to significant mercury ...
Artisanal Small-Scale Gold Mining . Artisanal gold mining refers to small-scale low-tech, informal activities focused on mining and processing ore to recover gold. Although AGM sites are individually small scale, collectively the sector comprises 20 percent of the world's gold production 2. Additionally it releases more mercury into the ...

Historically, mercury was used extensively in placer gold mining in order to form mercury-gold amalgam with smaller gold particles, and thereby increase the gold recovery rates. Large-scale use of mercury stopped in the 1960s. However, mercury is still used in artisanal and small-scale gold mining (ASGM), often clandestine, gold prospecting.
