Artisanal and Small-Scale Gold Mining Without Mercury ...

To separate gold particles from a concentrate, concentrate is fed into the centrifuge through a pipe at the top of the machine in a slurry of around 60-75% water and 40-35% solids. The material collects in a vessel in the center of the machine where high speed rotation creates force that moves the material up the sides of the vessel’s walls.

    The gold can be removed from the carbon by using a strong solution of caustic soda and cyanide, a process known as elution. Gold is then plated out onto steel wool through electrowinning. Gold specific resins can also be used in place of activated carbon, or where selective separation of gold from copper or other dissolved metals is required.
