摘要
通过对金离子在成矿溶液中的价态分析、水解分布和电化学歧化平衡计算等方面的讨论 ,从电化学和配位理论方面论述了在天然水介质中 ,金可能以Au(Ⅰ )与含硫配体形成的配离子形式迁移 ,其稳定性很高 ,从而进一步证明了配合物是金在成矿流体中存在的主要形态。
Ionic valence state of gold in mineralizing solution are discussed Through equilibrium calculation of hydrolysis and electrochemical divergent reaction, it is considered that stable state of gold ion may exist only being complex to form with Au(Ⅰ) and sulphur ligand, It is proven that ligand is main type of gold exiting in ore forming liguid [
