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 and Small-Scale Gold Mining Without Mercury. 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.
An artisanal miner or small-scale miner (ASM) is a subsistence miner who is not officially employed by a mining company, but works independently, mining various minerals or panning for gold using their own resources. Small-scale mining includes enterprises or individuals that employ workers for mining, but generally using manually-intensive methods, working with hand tools.
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'.
This sector is also responsible for the largest releases of mercury to the environment of any sector globally. A major source of air pollution from mercury, artisanal and small-scale gold mining releases approximately 400 metric tons of airborne elemental mercury each year.
Artisanal and small-scale gold mining Mercury amalgamation Clean technologies Sustainability abstract Artisanal and small-scale gold mining accounts for a significant portion of the current global gold market. Many artisanal gold miners use mercury to amalgamate gold and separate it from undesired gangue

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.

Technical alternatives for small-scale gold mining, however, must be thoroughly evaluated, pre-tested, modified accordingly and successfully transferred. Moreover, technology must be inexpensive, relatively simple and easy to adapt, while allowing a rapid rate of return.
mercury-based artisanal and small scale gold mining requires capacity building, which is currently lacking. Higher mercury prices (mercury rose ⅓ in the first 7 months of 2011 to $1900 per flask) can act as an economic incentive for miners to reduce mercury releases and can create demand for alternative technologies.
