Abstract A series of ex-situ precipitation experiments were firstly performed to investigate the effects of Eh/pH and impurity molar ratio on the transition of arsenic bearing precipitates from amorphous phase to crystalline phase. Based on the analyses of the ex-situ experiments, another series of in-situ precipitation experiments were designed and conducted to explore the effects of current density, circulation pattern, inlet position, seed crystals' concentration, and impurity molar ratio on the formation and growth of crystalline precipitates containing arsenic. It was found that higher Eh and pH values, as well as the impurity ratio of Sb/Bi

铜电解精炼过程中含砷结晶颗粒原位沉淀的研究

摘要 首先进行了一系列异位沉淀实验，研究了Eh/pH和杂质摩尔比对含砷沉淀物从非晶相向结晶相转变的影响。在对非原位实验分析的基础上，设计并进行了另一系列原位沉淀实验，以探讨电流密度、循环模式、入口位置、晶种浓度和杂质摩尔比对形成和沉积的影响。含砷结晶沉淀物的生长。发现较高的 Eh 和 pH 值，以及 Sb/Bi 的杂质比
