In particular, ionic rare earths are my country's precious, limited and non-renewable resources. They have the characteristics of high content of medium and heavy rare earth elements, simple extraction process and low radioactivity, and are an important supporting material in the field of high technology.
[0003] At present, the mining of ionic rare earths uses the in-situ leaching process of ionic rare earth ores. Liquid is injected from the top drill hole to penetrate into the ore layer for ion exchange and flow into the collection hole at the bottom of the mine to obtain rare earth mother liquor, which is then collected in each impurity sedimentation tank. After the impurity precipitation is completed, it is introduced into the rare earth sedimentation tank and added with a well-proportioned rare earth precipitation liquid for reaction precipitation. In this process, due to the deviation of rare earth content in each mountain, the purity of the collected rare earth mother liquor is also different, so it is necessary to test the rare earth mother liquor of each group of sedimentation tanks, and separately equip the rare earth mother liquor of each group of sedimentation tanks with rare earth precipitation liquid, which makes the overall rare earth mother liquor in the rare earth precipitation process node inefficient, resulting in uneven rare earth content in the finished product, which is not conducive to the purification of the later product.
