Currently, the thiosulfate gold leaching operation at the Goldstrike mine, Nevada, of Barrick Gold Corp is the only large-scale gold extraction plant with an alternate lixiviant (Azizitorghabeh et al., 2021). Although research on sulfur-containing lixiviants has been the most common in gold hydrometallurgy in the past three decades, few ...

Gold metallurgy is a technology for extracting gold and its compounds from gold ore, gold concentrate, or other gold-bearing materials. Gold is one of the earliest metals discovered and used, and its element symbol comes from the Latin aurum, with the original meaning "the glorious dawn".
In this study, a novel thiosulfate leaching system, cobalt-glycine catalyzed system, was proposed. DFT calculations suggest that the coordination ability of organic ligands with metal ions conforms to the order: glycine > oxalic acid > citric acid > acetylacetone, and the reactivity and adsorption capacity of complexes on gold surface …
cyanide process, method of extracting silver and gold from their ores by dissolving them in a dilute solution of sodium cyanide or potassium cyanide. The process was invented in 1887 by the Scottish chemists John S. MacArthur, Robert W. Forrest, and William Forrest. The method includes three steps: contacting the finely ground ore with the cyanide …

The concept of amine basicity is discussed and used to explain the selective extraction of gold from alkaline cyanide solution. The apparent basicity of simple weak base amines with respect to Au(CN) 2 can be increased as much as 5 orders of magnitude by the addition of organic phosphorus oxide compounds (TBP, DBBP, etc.). It has been …
