The gold carbon in pulp (CIP) Processing refers to the process of grinding all the gold ore into a slurry (-200 mesh content accounts for more than 90-95%). Cyanide leaching was carried out first, then activated carbon was used to absorb the Gold loaded carbon from the pulp, purification and smelting of the gold-loaded Gold in the medium ...

The grain size of the gravity recovery gold (GRG) in the ore was rarely considered. Despite the benefits of the AMIRA BCC Gravity Model being available since 2005, the cyclone underflow fed gravity circuit arrangement as an optimal configuration is still a preconceived design concept amongst gold processing metallurgists today.

So a 2% difference in cyclone efficiency actually – for the gold retention – actually does have a substantial difference on overall gold recovery in the circuit. So this is one of the reasons that one of the best things an operator can do to improve the gravity circuit is make sure that the cyclones are functioning very efficiently when it ...
