Gold CIL CIP Gold Leaching Process Explained CCD

2013-01-02  Carbon-in leach (CIL) is a simultaneous leach and absorption process. The simultaneous leach and absorption phases of the CIL process were developed for processing gold ores that contain preg-robbing materials such as natural absorptive carbon. These reduce the gold yield by attracting gold

Activated Carbon for Gold Recovery Puragen Activated Carbons

Gold Recovery Process. For gold recovery, water and a cyanide such as calcium cyanide, sodium cyanide, or potassium cyanide, are added to ore or scraps to form a slurry. The gold will leach out and mix with the cyanide into a solution. Activated carbon is then used to separate and store the gold, which is removed as the final step of the process.

GOLD RECOVERY FROM CARBON - MINTEK

This invention relates to the recovery of gold from carbon fines. Carbon fines are produced when carbon, which is used in a carbon-in-leach (CIL) or carbon-in-pulp (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.
