Get A QuoteThis invention relates to the recovery of gold from carbon fines.Carbon fines are produced when carbon, which is used in a carbon-in-leach cil or carbon-in-pulp cip process for the recovery of gold, is broken.Typically, these fines, loaded to some extent with gold, exit from a last adsorption stage of the process and are then lost.
Read More +A double refractory gold ore contains gold particles locked in sulphides, solid-solution in arsenopyrite, and preg-robbing material such as carbonaceous matter, and so on.The diagnostic leach test dlt and preg-robbing pr approaches are widely used to investigate the occurrence and the distribution of refractory gold.Dlt serves to qualitatively evaluate the gold occurrences within the ore.
