The governing method for gold ore processing has been cyanide leaching since the late 19th century (Marsden and House, 2006). After decades of active development of the process for various types of ores and concentrates, there are several different hydrometallurgical flowsheets for cyanide leaching. As ores differ greatly, the A novel porous gold polymer composite was prepared by the functionalization of a glycidyl methacrylate-based copolymer (pGME) with ethylene diamine (pGME-en), and activation by gold (pGME-en/AuA general overview of gold processing steps.

Combined Bacterial and Pressure Oxidation for Processing High-Sulfur Refractory Gold Concentrate. A. Boduen Maxim Zalesov V. Melamud Victoria Grigorieva A. Bulaev. Chemistry, Engineering. Processes. 2023. Microbially assisted bio-oxidation of sulfide concentrates in stirred-tank reactors (stirred-tank reactor bio-oxidation (STRB)) Processing of gold from refractory ores containing carbonaceous materials (CM) poses challenges due to the ability of the CM to preg-rob dissolved gold. Depending on the type and maturity of CM encountered, preg-robbing of aurocyanide ion can lead to reduction in gold recovery ranging from a few percentages to more than 50%. Preg-robbing of Gold by Carbonaceous Materials Encountered in Gold

The gold dissolution process comprises two fundamental stages, as depicted in Reactions 19 and 20: formation of Au(I) chloride on the gold surface, followed by the formation of AuCl 4 −. Stable oxidising conditions are required for adequate gold dissolution, which is followed by the precipitation of metallic gold ( Barbosa and Australian gold processing. Australia is currently the world’s second largest gold producer and hosts two of the world’s largest gold mines. It has a significant place in Australia’s economy and gold is the third largest mineral export after iron ore and coal.
