| 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. |
