本文提出了增加浸取液中交换剂的浓度;改变浸取液的表面性质,即加入1×10~(-3)%的表面活性剂;控制浸取液的酸度,都有利于提高和加快稀土的浸出。分析了杂质元素在浸出液中的分布情况及产品中的含量。试验结果表明:稀土的实收率可提高5%～15%,浸矿周期减少1/3,产品质量提高1%,生产费用降低。经初步工业性试验效果明显。 In this paper, it is proposed to increase the concentration of the exchangers in the leaching solution; to change the surface properties of the leaching solution, ie to add 1 × 10 -3% of the surfactant; to control the acidity of the leaching solution, Leaching of rare earths. Analysis of the distribution of impurity elements in the leaching solution and the content of the product. The test results show that the real yield of rare earth can be increased by 5% -15%, the leaching period can be reduced by 1/3, the product quality can be increased by 1% and the production cost can be reduced. The initial industrial test results are obvious.
