  Gold CIL process, Carbon in leach,Gold extraction process

  Gold CIL Production Line [Introduction]: Gold CIL process (carbon in leach) is an efficient method of extracting and recovering gold from its ore. By cyaniding and carbon leaching crushed gold ore slurry simultaneously, the CIL process lowers the gold mining operation cost and increases the gold recovery rate to 99%, which is the first choice of modern gold …
