(the same thing happens at coal-burning power plants, aarl carbon stripping system operation: elution elution stage. during this stage the gold and silver desorbed off the carbon during the preheat .* is washed out of the column into the eluate tank. this stage takes 2 1/2 hours and involves the use of 5 bed volumes of potable water (21.6 cubic metres).gold mining process development denver mineral engineersgold cyanide is adsorbed into the pores of activated carbon, resulting in a process solution that is devoid of gold. the loaded carbon is heated by a strong solution of hot caustic and cyanide to reverse the adsorption process and strip the carbon of gold. gold is then removed from the gold cil cip gold leaching process explained ccdgold cil cip gold leaching process explained ccd view larger image cyanide is a lixiviant, or reagent that is used to leach, often in tanks, gold from a solid matrix and form a gold cyanide complex.problems in processing goldintroduction to elution and carbon reactivation problems at elution of gold processing . gold extraction. gold extraction refers to the require further processing in order to recover the gold that would otherwise cause health and environmental problems due .
