酸度对浓硫酸法水浸液中的Fe、P浓度及中和前后稀土损失的影响

Effect of Acidity in Leaching on [Fe^(3+)],[P] and Rare Earth Loss of Counteract

研究水浸酸度对水浸液中Fe3+浓度、P浓度及中和前后稀土损失的影响,研究表明随着酸度增加,水浸液中Fe3+浓度和P浓度都有所增加,[Fe]/[P]有所下降,但它们的变化幅度不大。当[Fe]/[P]大于3时,酸度的变化对稀土中和损失没有直接影响。

The effect of acidity in leaching on , and RE loss of counteract was researched.The results indicated that following the increasing of acidity of steep, the concentration of , increased and /(the ratio of Fe to P) decreased with increasing acidity in leaching,but the range of change was not considerable.When / was bigger than 3,the change of acidity was no direct effect on RE loss of counteract.
