The dimensions of the column correspond to the 12 mm diameter gold elution columns with 9 g of activated carbon used by Van der Merwe and Van Deventer (1990) and Van Deventer and Van der Merwe (1994). The water inlet velocity was specified at between 0.09 and 0.15 mm/s (inlet boundary condition) depending on the flow rate of …
Elution and Goldroom plant
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:
