The real time optimization (RTO) of gold cyanidation leaching process has been investigated in this paper. To solve inevitable plant-model mismatch and process disturbance in practice, an RTO strategy based on SCFO (Sufficient Conditions for Feasibility and Optimality) for gold cyanidation leaching process is proposed, where the SCFO are used to enforce the …

Gold cyanidation is an electrochemical process, where gold is oxidized and then complexed to the stable complex ion [Au(CN) 2] −, oxygen is reduced, and hydrogen peroxide decomposed (Habashi, 1987, Yannopoulos, 1991, Marsden and House, 1992).A typical gold ore processing plant comprises comminution, size classification, gravity concentration, and …

Cyanidation or the leaching process in gold mining and the role of oxygen . Cyanidation, also known as the leaching process, is a widely used method in the mining industry for extracting gold and silver from ores. The oxygenation process enhances the efficiency of cyanidation and ensures maximum gold extraction and yield.

The results of the investigation strongly suggested that an alternative cyanidation route for the treatment of gold-plant concentrates was technically feasible, provided the system included effective agitation and oxygenation. In the case of lower-grade concentrates, cyanidation followed by the electrowinning of gold appears to be the sim-

The gold cyanidation process has certain requirements on the performance of the leaching (adsorption) agitation tank. Under the condition of small power consumption, the particles with monomer separation or exposed surface gold in the pulp cannot be deposited in the tank, and the pulp, cyanide, lime and air should be fully mixed in the tank to reach the suspension state.
