UTILIZING CYANIDE RECOVERY TECHNIQUES IN THE CESL GOLD ...
Cyanide in solution is combined with gold ore and leaches the metal to form a soluble cyanide gold complex. The gold is then typically adsorbed onto activated carbon for downstream recovery. The resulting barren solution, still containing cyanide but absent of gold, can then be recycled for reuse and leaching of new ore. However, many gold bearing ores also contain copper. The presence of ...
