Plants. On exception of the power consumption of comminution, the highest consumers of power within a gold processing plant are elution, carbon regeneration and goldroom unit processes. AZMET has developed and designed a state of the art engineering model to optimize gold elution circuit and designed/modeled containerised unit processes.
Gold Ore Processing. Carbon-in-pulp (CIP) consists of cyanide leaching and then absorption of gold from ore, which is considered a simple and cheap process. Using a CIP gold processing plant, pulp flows through tanks where sodium cyanide and oxygen help dissolve gold into solution. CIP plants are similar to Carbon-in-leach plants.
Elution and electrowinning pilot plant is the key equipment for the gold extraction by the method of cyanidation, CIP or CIL. It will desorp gold from activated carbon to concentrated gold solution. Electrowinning is a process used to recover metals gold from concentrated solutions. It is an ideal pilot equipment for gold extraction. Features:

The elution plant and goldroom completes the CIL/CIP/ CIC circuit, enabling stripping of gold from loaded carbon, electrowinning into gold sludge, and drying and smelting of sludge into doré bars. Carbon can then be reactivated for reuse in the circuit. Outotec's turnkey process plant solution includes:
— Once the activated carbon is loaded with gold, it's removed from the adsorption columns and goes through a process called elution to strip off the gold. The loaded carbon is treated with a hot (90-120°C) caustic solution containing 1-2% sodium hydroxide (NaOH) and 0.1-0.2% cyanide (NaCN).
