  • Artisanal and SmallScale Gold Mining Without Mercury

    Although many miners use mercury in artisanal and smallscale gold mining, it is possible to safely and economically recover gold without it. Mercuryfree techniques are safer for miners, their families and local communities. They may also help miners market their gold at higher prices. Many artisanal and smallscale miners are achieving highBallfree mechanochemistry: in situ realtime monitoring ,using liquidassisted grinding techniques.
