研究了以亚硫酸铵为还原剂,在酸性条件下从电解锰阳极泥中浸出锰和硒的工艺。考察了浸出温度、硫酸浓度、亚硫酸铵用量及反应时间对锰和硒浸出率的影响。结果表明,在硫酸浓度1.69mol/L、反应时间30min、浸出温度30℃和还原剂用量为12.0g的条件下,锰和硒的浸出率分别达到98.78%和93.94%。
Abstract：The process to leach manganese and selenium from electrolytic manganese anode slime with acidic ammonium sulfite as reducing agent was studied.Effects of leaching temperature,sulfuric acid concentration,ammonium sulfite dosage and reaction time on leaching rate of manganese and selenium were investigated.The results show that leaching rate of manganese and selenium is 98.78% and 93.94%respectively under the conditions including sulfuric acid concentration of 1.69 mol/L,reaction time of30 min,leaching temperature of 30℃,and reductant dosage of 12.0 g.
