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.

· A gold mine was under severe pressure because the gold grade of the ore body it was mining had fallen by around 20 percent. The mine had increased oreproduction volumes to try to offset the decline, but it was running into difficulties because this was overloading its leaching plant and incurring higher costs on energy, chemicals, and other major input costs.
Gold processing
· Gold 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 (, 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 piled into .
