摘 要：根据同时平衡原理，对氯盐体系硫化铋矿浸出过程和三氯化铋水解过程进行了详细的热力学分析，绘制了Bi2S3－HCl－H2O系E－pH图，E－[Cl－]T图和E－[Bi3＋]T图以及三氯化铋水解过程pH－[Bi3＋]T和溶解度－pH图，为铋湿法冶金提供重要的理论依据
Abstract: According to the principles of simultaneous equilibrium, the thermodynamic analysis of the Bi2S3 concentrate leaching process and the hydrolysis process of BiCl3 has been studied in detail in this paper. The E pH, E T and E [Bi 3+ ] T diagrams for Bi2S3－HCl－H2O system and the pH [Bi3+]T and BiOCl solubility pH diagrams for the BiCl3 hydrolysis process have been calculated and drawn by computer. The results would provide an important theoretical basis for the hydrometallurgy of bismuch.
