  Cyanide and Other Lixiviant Leaching Systems for Gold with …

  2010610 · Alkaline lixiviant systems (pH > 10)include cyanide, ammonia-cyanide, ammonia, sulphide, nitriles, and a few other minor possibilities. Oxygen is the main oxidant. Cyanide, which is the main ligand in these systems, forms an anionic complex, “Au (CN)2”, with Au (I). Gold dissolution rates are controlled by oxygen solubility in solution.

  Cyanide Antidote - an overview | ScienceDirect Topics

  Whether ingested or inhaled, cyanide is very lethal. Cyanide produces toxicity through impairment of mitochondrial enzymes, disrupting the electron transport chain, and preventing their utilization of oxygen. The mainstay of treatment of cyanide toxicity consists of the use of a multistage antidote kit.

  Cyanide process | Gold Extraction, Leaching & Recovery

  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 solution, …

  (PDF) Leaching of gold ores with high cyanicides: …

  201312 · Cyanide is a lixiviant, or reagent that is used to leach, often in tanks, gold from a solid matrix and form a gold cyanide complex. The gold cyanide complex is then extracted from the pulp or slurry by adsorption onto activated carbon. CIL stands for carbon-in-leach. This is a gold extraction process called cyanidation where carbon is added to …
