Sep 30, 2017· The ash will automatically limit the oxygen to the carbon by covering it. However full ashing is the first thing you must accomplish. Any carbon present will re-extract the gold if you try to dissolve it in a leach, and any carbon will float on the surface if you try to flux smelt it. A rotary kiln is a good idea.

Gold and silver are stripped from activated carbon on which they are adsorbed as cyanide complexes by subjecting the activated carbon to a stripping solution comprising as the strippant an effective amount of a compound containing the carboxylate functionality. The compound is preferably selected from benzoic and substituted benzoic acids, and …

movement of adsorbates (species that will be adsorbed by the carbon, e.g. gold) into the activated carbon granules. Mesopores (100 Å to 500 Å) these are the pores that branch off the macropores that serve to allow the adsorbates to leave the macropores Micropores (8 to 100 Å) which are of the right size to allow the adsorbates to be strongly

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.
