Artisanal and Small-Scale Gold Mining Without

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.
