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.
