Activated Carbon for Gold Recovery Puragen Activated Carbons

Activated carbon has long been used as an adsorbent in the gold processing industry to recover gold from mining operations. Due to its high surface area and exceptional hardness, coconut shell GAC (granulated activated carbon) is the main product used in carbon-in-leach (CIL), carbon-in-pulp (CIP), and carbon-in-column (CIC) operating systems.

Carbon in pulp

Carbon in pulp (CIP) is an extraction technique for recovery of gold which has been liberated into a cyanide solution as part of the gold cyanidation process. Introduced in the early 1980s, Carbon in Pulp is regarded as a simple and cheap process. As such it is used in most industrial applications where the presence of competing silver or copper does not prohibit its use.

- The carbon in pulp (CIP) process, The carbon in leach (CIL) process and The carbon in column (CIC) process. During the CIP process activated carbon particles are added to the leached pulp in a counter current circuit. The counter current principle is important because the amount of gold adsorbed on the carbon is in equilibrium with the
