| 摘 要： | 以电解二氧化锰过程中硫化除重金属的硫化渣为原料，基于热力学分析结果，以稀硫酸为浸出剂，辅以软锰矿协同氧化浸出硫化渣，以回收其中的锰、钴、镍有价金属。考察了矿渣比、始酸浓度、液固比、反应温度对锰、钴、镍浸出率的影响。结果表明，适宜条件为：温度363.15 K、矿渣比0.08、始酸浓度90 g/L、反应时间180 min，锰、钴、镍的浸出率分别为93.5%、87.4%、86.3%。

| Abstract: | Applying vulcanized slag of heavy metals removal by sulfurization during electrolytic manganese dioxide as raw material, dilute sulfuric acid as leaching agent, and based on thermodynamic analysis, Mn, Co and Ni were recovered by collaborative oxidation leaching with soft manganese ore. Effects of slag ratio, initial acid concentration, L/S, and reaction temperature on leaching rate of Mn, Co and Ni were investigated. The results show that leaching rate of Mn, Co and Ni is 93.5%, 87.4% and 86.3% respectively under the conditions including temperature of 363.15 K, slag ratio of 0.08, initial acid concentration of 90 g/L, and reaction time of 180 min. |
