activated carbon pulp cyanide gold extraction

Gold CIP process (carbon in pulp) is one of the gold ...

2020-5-20  CIP (carbon in pulp) gold extraction process is a method of adding activated carbon to the cyanide slurry, adsorbing the dissolved gold to the activated carbon, and extracting gold from the activated carbon. Gold CIP process eliminates the slurry washing and solid-liquid separation operations, directly uses granular activated carbon to absorb ...
