| 摘 要： | 在分析贵州织金新华含稀土磷矿石的化学成分和物相组成的基础上，依次进行了原矿的磨矿性能、重选和浮选试验。试验结果表明，重选试验难以达到分离富集有用矿物的目的，而采用一次粗选、一次精选的反浮选开路流程，则可使预富集稀土精矿中的磷富集约1倍，其稀土（REO）品位也由原矿的0.070%提高到0.135%，且稀土的回收率为83.87%。

| Abstract: | Based on the analysis of the chemical and mineralogical phase composition of Zhijin Xinhua rare-earth containing phosphorus ore in Guizhou, tests on its grinding property, gravity separation and flotation were made. The results indicate that it is difficult for gravity separation to realize the separation and enrichment of valuable minerals while the application of open reverse flotation flowsheet consisting of one roughing and one cleaning may double the phosphorus content in pre-enriched rare-earch concentrate with the rare-earth grade increasing from 0.070% in run-of-mine ore to 0.135% and the rare-earth recovery being 83.87%. |
