More recently a modified Zadra procedure operating at 140 °C in a pressurized system has reduced elution time to 10–12 h. In the AARL process, gold cyanideloaded activated carbon is contacted with 5% w/v sodium cyanide and 1% w/v sodium hydroxide followed by elution for 8–12 h with hot deionized water at 100–120 °C.

ELUTION BEHAVIOUR OF METALS FROM CARBON 475 Introduction Gold can be extracted industrially from ores by a variety of processes, and one of the most successful methods is the carboninpulp (CIP) process. In CIP processing, ore is mined, ground, and leached with alkaline cyanidic solution to solubilize the gold as a gold cyanide complex.

The Anglo American Research Laboratories AARL carbon stripping system used in this EXAMPLE has two definite advantages when compared with its most common counterpart, the Zadra system. It is much less expensive to operate and it produces a cleaner stripped carbon. It is however very reliant upon the availability of an abundant supply of good quality water and its water usage is far greater ...
