This is the process plant for the Agbaou Gold Mine. The Agbaou processing plant uses the conventional gravity/carbon in leach (“CIL”) gold recovery process. The comminution circuit of the process plant is comprised of a primary jaw crusher, followed by SAG and ball mills. A dedicated gravity circuit consisting of a concentrator, intensive cyanidation package and an electrowinning cell recovers free gold from a portion of the milled product. The rest of the milled product is processed in the CIL circuit where gold contained in the ore is leached and adsorbed onto activated carbon. The CIL tails slurry undergoes cyanide destruction prior to disposal in the tailings dam. Loaded carbon is acid washed and rinsed prior to elution. The electrolyte leaving the Anglo American Research Laboratory elution circuit undergoes electrowinning where gold sludge is produced. The sludge is dewatered using a pot filter and dried in a drying oven ahead of smelting. Fluxes are added to the dried gold sludge and the mixture placed in the smelting furnace. After smelting the furnace crucible contents are poured into cascading moulds. The gold bars are cleaned, sampled, labelled and prepared for shipping.
