Foramtion and Oxidation Mechanism of Sulfur in the Process of Slurry Electrolysis on Bismuthinite;

辉铋矿矿浆电解过程硫的形成及氧化机理

Through studying the diagram of potential-pH in Bi-S-H2O system and the microstructure of leaching fesidue,the leaching mechanism of bismuthinite is discussed,and the leach-ing reactions are mainly the redox reactions of Fe3+ and H2SoSo the reactio.

通过对石墨阳极极化曲线的研究，阐明了矿浆电解法在酸性氯盐介质中的阳极反应机理；在用热力学数据计算绘制Ｂｉ－Ｓ－Ｈ２Ｏ系的电位－ｐＨ图的基础上，借助于对过程浸出渣样的物相分析，探讨了辉铋矿的浸出机理。

A new bydrometallurgical process Slurry Electrowinni ng has been used for treating bismuthinite concentrates in the system of HCl一FeCl3-NaCl一H2O,and the leaching mechanism at the anode has been brought up upon systematic study.

石墨阳极反应主要是铁高子的转换反应，浸出过程主要是辉铋矿与盐酸的分解反应及三价铁和Ｈ２Ｓ的氧化还原反应，阳极浸出过程机理如下：Ｂｉ２Ｓ３＋６ＨＣｌ＋（２ｎ一６）Ｃｌ－＝２ＢｉＣｌｎ（３－ｎ）＋３Ｈ２Ｓ（ｎ＝１￣６）２Ｆｅ３＋＋Ｈ２Ｓ＝２Ｆｅ２＋＋Ｓｏ＋２Ｈ＋Ｆｅ２＋－ｅ＝Ｆｅ３＋阴极发生铋的沉积：Ｂｉｃｌｎ（３－ｎ）－３ｅ＝Ｂｉ＋ｎＣｌ－（ｎ＝１～６）Ｆｅ３＋＋ｅ＝Ｆｅ２

Al so, the dsta was compared with of tetradymite and kawazulite (in JCPDS cards) in this Paper,it is found that the tetradymite in this paper is similar to kawazulite but defferent to the for mer tetradymite in JCPDS cards.
