| 摘 要： | 在分析浸金体系基础上,推导浸金过程的热力学判据,提出浸金的平衡常数判据,讨论浸金体系氧化剂和络合剂的关系。浸金体系氧化剂的电位判据和金(Ⅰ/Ⅲ)络合物的稳定常数相关,稳定常数愈大,该浸金体系所需氧化剂的最小氧化电位愈小。

| Abstract: | The thermodynamic and the equilibrium constant criterion of the gold leaching process is deduced and proposed on the basis of analysis of gold leaching systems.The relationship of oxidants and ligands in gold leaching systems is discussed.The gold leaching process with the oxidant may proceed in thermodynamics.The electrical potential criterion of the oxidant in gold leaching systems is related to the stability constant of gold(Ⅰ/Ⅲ) complexes.The stability constant is higher,and the minimum electrical potential needed for the oxidant in the gold leaching systems is lower. |
