Reducing Mercury Artisanal Gold Mining
1. Gold can represent an excellent method of transferring wealth to rural communities: small-scale 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 small-scale gold mining (ASGM) needs to be brought into the

Method of Gold Extraction using Borax -Small Scale Miners No Mercury
Gravity Borax Method GBM Mercury Free Gold Recovery. The Gravity-Borax Method GBM is still unknown to most Artisanal and small-scale gold miners (ASGMs) worldwide as most still use mercury to extract gold. “Whole-ore amalgamation ” is a technique that requires the use of 10–25 g of mercury to produce 1 g of gold.

Concentration of Gold Ores
Concentration of Gold Ores – a Key to Reducing Mercury Use in Artisanal and Small Scale Gold Mining. Posted 3rd June 2012 by Kevin Telmer. In artisanal gold mining, mercury is essentially used to concentrate the gold. It does this by bonding with the gold to form a heavy amalgam that is then easily separated from the other minerals. It

Heavy Metals in the Soils of Placer Small-Scale Gold Mining Sites in
Background: Artisanal and small-scale mining activities are widely practiced globally. Concentrations of heavy metals associated with gold, such as copper (Cu), zinc (Zn), arsenic (As), cadmium (Cd), mercury (Hg) and lead (Pb) can increase in the environment as a result of mining activities, leading to environmental pollution and pose toxicity risks to humans and animals.
