| 摘 要： | 通过测定不同条件下石墨阳极化曲线和浸出渣样的物相分析，查明复杂锑铅矿矿浆电解的阳极反应机理，由于含铁矿物自生FeCl3的氧化，硫锑铁矿的氧化性格合酸分解和脆硫锑铅矿的非氧化性格合酸溶及夹带空气的氧化，锑铅矿中锑的直接酸溶浸出率达35%，通入锑的理论浸出电量，可以使锑，铅和铁完全氧化浸出，锑铅矿矿浆电解的阳极过程是硫化物中硫原位失电子和金属阳离子向溶液中扩散的过程。

| Abstract: | The anodic reaction mechanism of the complicated antimony lead concentrate in slurry electrolysis is investigated by the anodic polarization curves determining under various conditions and the mineralogy study of the slurry electrolysis residue The direct leaching rate of the antimony acid dissolution is up to 35% by means of the oxidation reaction of FeCl 3 produced from antimony lead concentrate, the non oxidation acid dissolution of jamesonite, the oxidation acid dissolution of gudmundite, and the oxidation of air carried by stirring All of antimony, lead in the antimony lead concentrate are completely dissolved by use of the theoretical coulomb in the slurry electrolysis process The slurry electrolysis of the complicated antimony lead concentrate is the electron lose of the sulfur in stiu and the diffusion process of the anodic ions in the sulfide minerals |
