Desorption electrolysis system [Introduction] A complete set of system is applied to the treatment of gbearing charcoal in the coal pulp plant of g mines, so that g can be separated from the gbearing charcoal and precipitated into highgrade g sludge. [G Carbon Content] Over 3.5kg/t [Application] It is used to extract solid g from gbearing carbon by cyanidation.

The carbon in the reactor into which pregnant pulp is fed (referred to as the first reactor) becomes highly loaded with g. Loaded carbon values on operating plants range from 300 to 20 grams of g per ton of carbon, a concentrating factor of about 1 1 500. A portion of the loaded carbon is periodically removed from the first adsorption
