It is found in either sulphide or laterite type ores so analytical methods are needed to ensure complete digestion. Note: Refer to the Exploration Grade Analysis section in this guide for descriptions of the GE_ICP21B20, GE_ICP40Q12, GE_ ICP90A50 digestion techniques. For description of the GO_ICP21B100, GO_ICP42Q100 and GO_ICP90Q100 techniques, please see the Ore-Grade Analysis section.
