摘　　要：基于辉铋矿矿浆电解渣的工艺矿物学研究 ,通过有关热力学的分析和阳极电化学的研究 ,探讨了辉铋矿矿浆电解过程元素硫的形成及氧化机理。元素硫是由辉铋矿经酸络合分解生成H2 S ,H2 S再被Fe3 +氧化而形成的。矿浆电解时 ,元素硫在阳极上基本不被氧化。Based on the mineralogical study,thermodynamics analysis,and anode electrochemistry study,the formation and oxidation mechanism of sulfur in the process of Slurry Electrolysis on bismuthinite had been studied.The formation of sulfur is through the redox reaction of Fe 3+ and H 2S forming by non-oxidative acid dissolution of bismuthinite.In the process of Slurry electrolysis,the oxidation of sulfur on the anode is less.
