1. Gold can represent an excellent method of transferring wealth to rural communities: smallscale producers often get 70% or more of international prices, even in remote areas. This is much higher than other products such as coffee, bananas, etc. 2. Artisanal and smallscale gold mining (ASGM) needs to be brought into the
Mercury‐dependent artisanal and small‐scale gold mining (ASGM) is the largest source of mercury pollution on Earth. In this practice, elemental mercury is used to extract gold from ore as an amalgam. The amalgam is typically isolated by hand and then heated—often with a torch or over a stove—to distill the mercury and isolate the gold.
The real impact of mercuryreducing technology in smallscale gold mining. Updated: Sep 11. Evidence of the very real difference that the Impact Facility is making in mining communities across the world comes from Cyrus Maina, our regional manager in East Africa in charge of equipment installations and mine engagement.

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 "paystreak". Paystreaks always form along the gold path where the river''s flow slows down on a large scale during a major flood storm.
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 ...
