摘　　要：通过脆硫锑铅矿矿浆电解渣工艺矿物学研究和有关热力学和电化学的分析 ,探讨元素硫形成及氧化机理。结果表明 ,元素硫是脆硫锑铅矿与Fe3+ 接触氧化的反应产物 ,脆硫锑铅矿分解生成H2 S再被Fe3+ 氧化的反应是次要的。矿浆电解时 。Based on mineralogical study, thermodynamics and anode electrochemistry analysis, the formation and oxidation mechanism of sulfur in the Slurry Electrolysis Process of jamesonite is investigated The formation of sulfur is through the redox reaction of Fe 3+ and jamesonite The redox reaction of Fe 3+ and H 2S forming by non oxidative acid dissolution of jamesonite is negligible In the Slurry Electrolysis Process, the oxidation of sulfur on the anode is negative

关 键 词：脆硫锑铅矿 矿浆电解 硫
