为回收织金磷矿中的稀土资源,进行了用磷酸分离织金磷矿中磷与稀土的试验研究。介绍了试验原理、工艺流程。试验结果表明,磷浸出率大于95%,约83%的稀土富集在渣中,渣中稀土氧化物质量分数大于50%,达到了分离磷与稀土的目的。 In order to recover the rare earth resources in Zhijin phosphate rock, the phosphorous acid was used to separate phosphorus and rare earth from Zhijin phosphate rock. Introduced the test principle, process. The results show that the phosphorus leaching rate is more than 95%. About 83% rare earth is enriched in the slag, and the mass fraction of the rare earth oxide in the slag is more than 50%, which achieves the goal of separating phosphorus and rare earth.
