  • Cyanide Process Gold Cyanidation Process | Gold Leaching

    Cyanide Process – Extraction Of Gold Through Cyanidation Gold is usually found in low concentration in the form of ore which is mined Gold should be separated from other minerals present in the ore As gold is insoluble, it should be separated from other minerals to make it soluble Hence, sodium cyanide can be added, where cyanide ions form a complex ion withHere I present an Process EXAMPLE of Gold Extraction Cyanide in which the cyanidation feed consists of a pyrite concentrate floated after the selective flotation of a coppergold concentrate The pyrite concentrate is reground to 90% minus 325 mesh and aerated in a highlime solution prior to cyanidation It contains 99% sulphides of which 10 to 20 percent is pyrrhotite and 03Process of Cyanide Gold Extraction
