Cyanide process, also called Macarthurforrest 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.
process are gold leach efficiency and cyanide consumption as a function of the fineness of grind and other leach conditions. REFRACTORY GOLD ORE PROCESSES ''Refractoriness'' results in poor gold recovery by standard processing techniques, and can be due to either chemical or physical interference. An example of chemical interference is the

Gold is processed by cyanide milling, a chemical procedure that separates 95 to 98 percent of the gold from raw mined ore. It is then refined to the gold standard purity, according to Mineweb. Heap leaching is a less expensive method of gold extraction, but it is a longer process and it recovers less gold than the cyanide milling process.
