  • Recovery of gold from carbon fines Hydrometallurgy

    The same striping method that work for loaded carbon work for carbon fines, the issue is the retaining the carbon in the strip vessel Zadra and AARL methods work and there are other methods such as alcohol that can be done at atmospheric pressure You cant just strip the carbon with cyanide in a tank, at least not very effectively Most people smelt their carbon fines to recovery the gold byMost mines do not have the refining capacity to separate the silver from the gold and the bars are sent to a commercial refinery for producing the 9999% gold and silver ingots that are sold on the commercial gold market Once the carbon has been stripped, it can be reused after recharging it in a kiln, by heating it to around 1300 degrees F The carbon is then cooled, screened to remove finesCarbon Adsorption In Recovery Of Gold Mine activated carbon I drives the equilibrium in the leaching step forward I separates the solid gold, Au (s), from the pulp (slurry) I obtain C A,S ˘8000 grams of Au per tonne of carbon IDesorption: I separate the highly concentrated goldcarbon pulp (screens/ lter/ cyclones/sedimentation) I desorb the gold o the carbon with caustic contactSeparation Processes: Adsorption
