摘　　要：新华磷矿高山矿段位于新华磷矿南西段,区内磷矿品位不高,但伴生稀土,前人对稀土与磷的富集规律做了相关研究,但缺乏矿区内样品的系统统计分析,本文利用普查样品测试结果,采用“Excle”软件的分析统计功能,对稀土与磷矿之间的富集规律进行总结探讨,P_(2)O_(5)品位走向上从北东到南西变低,倾向上地表含量高深部含量低,纵向上矿层上下部含量较高、中部含量低。稀土含量与磷含量具有较强的正相关,相关系数0.63-0.66。The Gaoshan ore section of Xinhua Phosphate Mine is located in the south-west section of Xinhua Phosphate Mine.The grade of phosphate ore in the area is not high,but it is associated with rare earth.Previous researchers have done relevant research on the enrichment law of rare earth and phosphorus,but lack of systematic statistical analysis of samples in the mining area.This paper uses the test results of census samples and the analysis and statistical function of"Excel"software to summarize and discuss the enrichment law between rare earth and phosphate ore.The P_(2)O_(5) grade tends to decrease from northeast to southwest,The surface content is high in the upper part and low in the deep part,and the content in the upper and lower parts of the ore bed is high in the longitudinal direction,and the content in the middle part is low.There is a strong positive correlation between rare earth content and phosphorus content,with a correlation coefficient of 0.63-0.66.
