A method for controlling the extraction of gold from a gold ore by the cyanidation process in which a leaching step including the addition of a lead compound which is typi cally lead nitrate or other lead salt is used In order to maintain stable conditions in the leaching process and to use the leaching reagents efficiently an analysis step is
