摘要
Ｒｅ是一种重要的分散元素。本文通过对５１２可地浸砂岩型铀矿床中Ｒｅ的地球化学特征进行分析，指出Ｒｅ的活化迁移和沉淀富集受地球化学环境控制，并与有机质密切相关，其赋存形式以ＲｅＯ＿２和有机质吸附为主。同时指出Ｒｅ在该铀矿床中已达到地浸开采综合利用的指标，建议加强对其地浸工艺的研究。
Rhenium is a very important dispersed element. By analysis of geochemical characteristics of Re in in-situ leachable sandstone-type uranium deposit No. 512,this paper concludes that the remobilization, transportation, precipitation and enrichment of rhenium are clearly controlled by geochemical environment and closely related to organic matter. Rhenium occurs mainly in the form of ReO2 and is absorbed by organic matter. The content of rhenium in uranium deposit No.512 reaches the level of comprehensive utilization. Finally the authors suggest that further study on extracting rhenium during in-situ leaching be strengthened.
