  • Gold Recovery And How To Choose The Right Process

    Gold Recovery And How To Choose The Right Process

    Gold ore is considered free-milling when it is easily liberated by grinding and separated from the other minerals. A more technical definition is that you are able to recover over 90 of the gold by a conventional gravity-cyanidation process with low reagent consumption. Free-milling gold can be further classified into low grade and high grade ...

    Artisanal And Smallscale 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 vessels walls.
