The gold-bearing solution is pumped from the “pregnant” holding pond to the ADR plant. The solution flows through the carbon in the center of these cylinders. The gold clings to the carbon which is then removed and processed to extract the gold, and the remaining solution is pumped back to the “barren” holding pond to be reused on the recovery pad.

The carbon and remaining solution are all regularly tested to ensure complete removal and absorption of the gold content.
