  • Concentration of Gold Ores Artisanal Gold Council

    20/12/2021  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 follows therefore, that if mercury is used as a mechanism of concentration, producing concentrates of gold ores through other means can enable reduction or even elimination of Concentration of Gold Ores Nature WHEN gold mining is a new industry in any country, the methods of extraction are often somewhat rough and ready With great quantities of Concentration of Gold Ores Naturegold processing gold processing Mining and concentrating: The nature of the ore deposit determines the mining and mineral processing techniques applied Oxide ore deposits are frequently of such low grade (eg, 3 to 10 parts per million) that extensive mineral processing cannot economically be justified In this case they are merely shattered by explosives and then gold processing Mining and concentrating Britannica
