A successful full-scale production trial of Australia-developed grade engineering techniques is paying dividends for a South American mine, and its local workers, according to CRC ORE. Once fully implemented, this is expected to generate an additional A$451 million ($312 million) in profit for the mine and reduce its energy consumption, it said.

A slurry of ground ore, water and a weak cyanide solution is fed into large steel leach tanks where the gold and silver are dissolved. 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.

These New World mines, much richer in silver, resulted in the rise of South and Central America as the largest silver-producing areas in the world. For the recovery of New World silver, the Patio process was employed. Silver-bearing ore was ground and then mixed with salt, roasted copper ore, and mercury.
