Application of Inductively Coupled Plasma-Atomic Emission Spectrometry/Mass Spectrometry to Phase Analysis of Gold in Gold Ores

We established a method of ICP-AES/MS applicable to the chemical phase analysis of gold in batch form. Parameters and procedures for the method were determined, including sample preparation, sample amount, dissolution and separation of total gold and 4 phases of gold (FAu, LAu, SAu and AAu). The optimum analytical conditions of ICP-AES/MS were also determined. The method was verified by using rock-mineral identification, VOL-AAS and GFAAS. 111
