movement of adsorbates (species that will be adsorbed by the carbon, e.g. gold) into the activated carbon granules. Mesopores (100 to 500 ) these are the pores that branch off the macropores that serve to allow the adsorbates to leave the macropores Micropores (8 to 100 ) which are of the right size to allow the adsorbates to be strongly

Gold processing Mining and concentrating Britannica

Gold processing Mining and concentrating Britannica

Gold processing - Gold processing - Mining and concentrating: The nature of the ore deposit determines the mining and mineral processing techniques applied. Oxide ore deposits are frequently of such low grade (e.g., 3 to 10 parts per million) that extensive mineral processing cannot economically be justified. In this case they are merely shattered by explosives and then piled into heaps for ...

Carbon Elution Strip System for precious metal recovery

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.
