GOLD RECOVERY FROM CARBON

GOLD RECOVERY FROM CARBON

Carbon fines are produced when carbon, which is used in a carboninleach (CIL) or carboninpulp (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.

A method for recovering gold from goldloaded fine carbon residue from a coarse carbon gold recovery process is disclosed. The goldloaded fine carbon residue is mixed with activated coarse carbon and an aqueous solution of a transfer reagent to form a slurry. In the slurry the reagent promotes transfer of gold from the fine carbon to the coarse carbon.

These carbon recovery techniques include: The ore is crushed, finely ground and mixed with the cyanide leach solution to form a slurry in an agitation tank. The activated carbon is introduced into the slurry and then removed by screening once it is fully loaded or "pregnant" with gold. This process is very similar to the CIP process.

Leaching dissolves the gold out of the ore using a chemical solvent. The most common solvent is cyanide, which must be combined with oxygen in a process known as carboninpulp. As the cyanide and oxygen react chemically, gold in the pulp dissolves. When workers introduce small carbon grains to the tank, the gold adheres to the carbon.
