Activated Carbon in Gold Cyanidation

Activated carbon is a critical component in the beneficiation of gold ore, allowing this widespread process to occur because of its ability to recover gold from the gold-cyanide complex. Depending on the deposit, some silver ores may also be processed via cyanidation. Here too, activated carbon is the catalyst for recovery of this precious metal.

Carbon in pulp

 · Carbon in Leach vs Carbon in Pulp: Carbon-in-pulp (CIP) 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.

Carbon Adsorption

The carbon is then removed by screening, across a carbon screen, allowing the liquid and finely ground ore (-100 mesh) to pass through easily, and retaining the carbon on the screen. The carbon is then generally subjected to a heated solution (200 deg to 250 deg F) of (1%) sodium hydroxide and (0.1%) cyanide and the gold is re-dissolved and removed from the carbon …

Glossary of Mining Terms

Carbon-in-pulp - A method of recovering gold and silver from pregnant cyanide solutions by adsorbing the precious metals to granules of activated carbon, which are typically ground up coconut shells. Cash flow - The net of the inflow and outflow of cash during an accounting period.

Pulp and Paper – Analysis

Since pulp and paper products are highly traded, measures will be needed to help ensure a level playing field if the strength of policy efforts differs from one region to another. Possibilities include adopting border carbon adjustments or the free allocation of allowances for emissions below a targeted benchmark in an emissions trading system.
