摘要
Abstract
Aiming at the problem of low manganese leaching and recovery in the current electrolytic manganese metal liquid-making process,this paper takes the liquid-making process as the research object,carries out the simulation experiments of the existing industrial production liquid-making process(T1),anode liquid leaching(T2),anode liquid leaching-washing(T3)liquid-making process,and researches the influence of different liquid-making processes on the leaching and recovery of manganese in manganese ores,as well as on the migration of calcium,magnesium and iron.The results showed that the manganese leaching rate was T3(92.76％±0.40％)≈T2(92.14％±0.62％)＞T1 were carried out to study the effects of different liquid preparation processes on the leaching rate and recovery rate of manganese and the migration of calcium,magnesium and iron in manganese(89.59％±2.43％),and the manganese recovery rate was T3(91.18％±0.47％)＞T2(87.02％±0.74％)＞T,(73.97％±2.37％),indicating that the leaching rate and recovery rate of manganese in manganese ore can be effectively improved by anodic leaching,and the recovery rate of manganese leaching can be effectively improved by washing process.On the basis of the existing liquid production process,the anodic leaching process will not increase the migration proportion of calcium and magnesium in manganese ore to the liquid phase,but will increase the migration proportion of iron,and the addition of the washing process will not increase the migration proportion of calcium and iron in manganese ore to the liquid phase,but will increase the migration proportion of magnesium.关键词
