Carbon in Pulp - JXSC Mining

2021-5-11  Carbon in pulp process. Gold Carbon-in-pulp (CIP) production is the sequential leach, then absorption of gold from ore. During the CIP stage, pulp flows through several agitated tanks where sodium cyanide and oxygen have been added to dissolve gold into solution. CIP process is suitable for the treatment of oxidized gold ore with low sulfur content and mud content.

Carbon-in-Pulp - ScienceDirect

2016-1-1  In the Pica procedure, a sample of carbon is contacted for 1 h with 1 L of 10 mg/L gold solution. Residual gold in solution is measured, and gold adsorbed on to the carbon is calculated as G1. The carbon is recovered and put into a new fresh batch of 10 mg/L gold solution for a further hour. Gold adsorbed on to the carbon is calculated as G2.

DYNAMIC SIMULATION OF THE CARBON-IN- PULP AND

2008-2-12  In the carbon-in-pulp process adsorption occurs after the leaching cascade section of the plant, and in the carbon-in-leach process leaching and adsorption occur simultaneously. In both processes the activated carbon is moved from one tank to another in countercurrent with the ore pulp until the recovery of the loaded carbon in the first tank.

Recovery of gold by a carbon-in-pulp process -

A process for adsorbing gold from a leach pulp by means of activated carbon is described in which the leach pulp (the leach solution together with the subdivided gold bearing ore) is diluted to a specific gravity of less than that of the activated carbon and is subsequently passed upwardly through a multistage liquid/solid contacting column.
