  • THE RECOVERY OF PLATINUM PALLADIUM AND GOLD FROM A Cyanide Leaching Mining SGS

    The use of ion exchange resins for the recovery of gold and silver from pregnant cyanide leach solutions has been widely investigated over the past three decades as an alternative to the carbon in pulp CIP recovery process 1 7 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 ores
