Cyanide Leaching | SGS South Africa

During the cyanide leach process, a cyanide solution, or lixiviant, is percolated through ore contained in vats, columns or heaps. Gold is dissolved by the cyanide and then removed from the heap or columns. It is then extracted from the pregnant leach solution by adsorption on carbon or resins. This cost-effective, proven method of ore extraction provides maximum recovery for many gold …
