Analysis of the gold recovery profile through a cyanidation plant
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 …
Two-Stage SART Process: A Feasible Alternative for Gold Cyanidation …
Indeed, the two-stage SART plant reaches its optimum condition when the OR parameter defined in this study is close to 1.0. Summarizing, this SART option could be an excellent solution for gold cyanidation plants with Merrill–Crowe process installed in their flow-sheets which additionally contains high cyanide-soluble copper ores.
