Following this leaching process the slurry passes through six adsorption tanks containing carbon granules which adsorb the gold and silver. This process removes 93% of the gold and 70% of the silver. 6. Elution Electrowinning The loaded carbon is fed into an elution column where the bullion is washed off. The barren carbon is recycled.
