what process is used to extract gold from earth
Amalgamation is the gold extraction method most often used in artisanal, or small-scale, gold mining. Although amalgamation is a simple and effective way to isolate gold, it results in the release of mercury, a toxic substance, into the environment. In amalgamation, miners bring crushed ore into contact with mercury.
