Study All the Important Characteristics of Your Electrodeposition Cells. Modeling and simulations are cost-effective methods for understanding, optimizing, and controlling electrodeposition processes. A typical simulation yields the current distribution at the surface of the electrodes, and the thickness and composition of the deposited layer.
Gold-rich sludge will be washed off the steel cathodes in the electrowinning cells and then filtered, dried, and mixed with fluxes before being smelted in an electric induction furnace to produce the final gold dore bars. The leach-adsorption tails will be treated for cyanide destruction, thickened and deposited in the tailings management facility.
