Live ChatA 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 typically 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 used to monitor the concentration of
Live Chat201419Similarly cyanidation tests showed that almost 100 gold recovery was possible at high cyanide concentrations so that this sulphide ore is not refractory. 2.2. Analytical techniques Elemental concentrations in solutions were determined by ICPOES involving the oxidation of sulphur species to stable sulphates prior to the analysis.
Live ChatThe Cyanidation Process or CYANIDE LEACHING is most notably used in the recovery of gold. Safety and environmental concerns are of prime importance in the operation of a cyanidation plant. As we get farther into this type of recovery you will see why. The preparation of the ore for
