南方稀土矿浸出过程中，铝是影响产品质量的主要杂质。通过在矿石浸出剂中添加铝抑制剂来降低铝的浸出量进行了研究。优化试验结果表明，浸出剂中添加0.05%的HZA抑制剂，控制pH值为5.5，浸出液中的铝含量降低了56.85%，对稀土回收率影响不大。
In the course of southern RE ore leaching,Al is the major impurity affecting the product quality.Study is made of Al inhibition by addition of Al inhibitor in the ore leaching reagent to reduce leached Al.The optimization test results showed that Al in the resultant leachate is reduced by 56.85% by adding 0.05% HZA inhibitor in the leaching reagent and at controlled pH value 5.5 with little influence on RE recovery.
