The myth of gravity concentration to eliminate mercury

When analyzing gold in screened tailings from primary ores it is frequently observed that the majority of gold lost in gravity concentration processes used by artisanal miners is in the coarse and fine grain sized fractions Andrade Lima et al 2008 Gold in the coarse fractions represents the unliberated gold while gold in the fine fractions represents the fine gold particles that are not
