cyanidation of a pyrrhotite bearing gold ore

The effect of grinding chemistry on cyanide leaching of ,The Effect of Increasing Capacity on Gold Recovery and

For that reason, cyanide gold leaching is very efficient when ceramic or high chromium media was used during the grinding of the ore It can be expected that the leach behaviour would be different if leaching is preceded by pre-oxidation, as is often done for pyrrhotite bearing orKey words: Suboptimal , Cyanidation, Gold, Experimental Design, Tagouchi Background: Usually the cyanide salt such as sodium cyanide, potassium cyanide and calcium cyanide is used as a gold , The effect of these parameters on gold recovery in Aghdarreh ore is investigated using the Tagouchi method.
