about 2 bed volumes per hour at about 200 deg-F. Gold that was previously adsorbed on the carbon as a sodium or calcium/gold cyanide ion pair (2) is desorbed from the carbon by a reversal of the adsorption kinetics. Gold is recovered from the pregnant strip solution by electrowinning onto steel wool.
