Gold Elution Carbon Strip Plant Design

Carbon Elution/Strip System for precious metal recovery

The main advantage of the AARL process is the ability to strip a batch of carbon to low gold residuals in an average strip time of 6–8 hours compared with 6–10 hours for standard Zadra. New plants can be designed with multiple daily stripping cycles in mind, or existing plants can have increased daily capacity by adding shifts for stripping.

Strategies for the optimisation of gold processing plants

For efficient stripping of gold, from activated carbon, reversing the above is logical. Thus successful elution should be favoured by high temperature, high free cyanide, high pH, low ionic strength and the absence of calcium. This is an excellent starting point to commence elution optimisation.
