摘　　要：本文研究了自然金及常见矿物在Na_2S_2O_3-CuCl_2-NH_4OH-NH_4Cl体系中的溶解行为,对方法条件和主要影响因素也进行了研究,提出了金的化学物相分析新方法.In this paper, the various method of chemical phase analysis of gold in ores and applicable condition and influencing factor of each method were discussed. Through investigation of the digestion behavior of native gold and common minerals in the system of Na2S2O3-CuCl2-NH4OH-NH4C1, the sodium thiosulfate method for chemical phase analysis of gold in ores was put forward by the authors of this paper.
