  • Artisanal and SmallScale Gold Mining Without Mercury

    A centrifuge is a vessel that rotates about a central point. It is used to separate materials in a mixture by density. 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 6075% water and 4035% solids.
