An obvious drawback of this method is the toxicity of mercury.2, 3 The health risk of mercury is well known today in many parts of the world, but in remote small-scale mining (SSM) communities that knowledge is still scarce.4 Gold extraction by amalgamation releases large amounts of mercury into the environment as metal mercury, which is later ...
One of the most widespread gold extraction methods used by small-scale gold miners is whole ore amalgama-tion. In brief the method is as follows. After gold ore is mined, it is crushed to about walnut size mostly by hand. The crushed material is transferred to a metal drum and milled with hard metal rods or balls together with water and 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. This process can be very dangerous and lead to significant mercury ...

Jul 02, 2015· The History of Mercury and Gold Extraction . The first use of mercury in a large scale mining process was 1828 but evidence suggests that the use of mercury to extract gold from ore may have been first used over a thousand years ago. It is popular among small scale prospectors because it is cheap and simple to use.
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.
