中文摘要: 采用黄钠铁矾和硫化锰沉淀法从软锰矿硫酸浸出液中分步去除Fe3+、Co2+、Ni2+。先采用黄钠铁矾法沉淀去除Fe3+,再采用硫化锰沉淀去除Co2+、Ni2+。单因素试验最佳工艺条件为:隔氧环境下,MnS添加量10 g/L、反应温度75 ℃、反应时间30 min、转速120 r/min,此条件下,Co2+去除率达99.2%,Ni2+去除率达99.81%。
Abstract:Fe3+, Co2+ and Ni2+ were removed from pyrolusite sulfuric acid leaching solution by sodium jarosite and manganese sulfide precipitation method. Fe3+ was removed firstly by sodium jarosite, and Co2+ and Ni2+ were removed by manganese sulfide precipitation. Removal rate of Co2+ and Ni2+ is 99.2% and 99.81% respectively in an oxygen-proof environment under the optimum conditions including MnS addition of 10 g/L, reaction temperature of 75 ℃, reaction time of 30 min, and stirring speed of 120 r/min.
