Optimising cyanide:oxygen ratios in gold cip/cil circuits
A method has been developed to optimise the cyanide:oxygen ratio in gold CIP/CIL circuits. A gold (96%)/ silver (4%) alloy disc electrode is placed in the leaching pulp and its corrosion potential measured against a reference electrode. The electrode is then rotated in the pulp to increase the diffusion rate of cyanide and/or oxygen to the ...

Carbon-in-pulp (CIP) is the sequential leach then absorption of gold from ore. During the CIP stage, pulp flows through several agitated tanks where sodium cyanide and oxygen have been added to ...
Gold losses by cementation and thermal reduction in the gold recovery …
Gold was found in two main forms, as attached to iron bearing particles and in the form of dendritic particles. The findings suggest that such losses are likely in the CIP-cyanidation gold recovery circuits and therefore close control over the process should be maintained to minimize these losses.
Gold Ore Processing Plant Leaching Circuit
The ore flow rate time evolution was measured in the entrance of the comminution-leaching section of the plant, but not in the leaching-adsorption circuit entrance ( Bax, 1996 ); therefore, estimated values were produced by assuming that the comminution circuit behaves as a second order system with a time constant of 0.37 h.
Elution and Goldroom plant
The Elution and Goldroom plant 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. 's turnkey process plant solution includes:
