铀尾砂中植物采铀方法研究

以我国南方某铀尾砂库及其中生长的优势植物为研究对象, 通过测试分析铀尾砂中及优势植物体内的铀含量, 筛选出了铀的超富集植物--水莎草, 其茎中的铀含量高达1.520‰。据此, 提出了铀尾砂中植物采铀方法。这一方法的提出, 将极大地促进铀尾渣、铀废石、铀矿化土壤及低品位铀矿植物采铀方法的研究。

Study on Phyto-uranium Mining from Uranium Mill Sand

Using an uranium mill sand pond in the south China and the dominant plant grown in it as the object of study, the uranium hyperaccumulator juncellus serotinus was selected by testing and analyzing uranium content in uranium mill sand and dominant plant, which the content of uranium in the stem reached as high as 1.520‰. The method of phyto-uranium mining from uranium mill sand was proposed and it will promote the study on phyto-uranium mining from uranium mill dregs, uranium waste ore, uranium mineralized soils and low-grade uranium ore.
