某铀矿床主要岩石浸泡试验

Immersion Test of Main Rocks in a Uranium Deposit

某铀矿床主要出露黑云母斜长片麻岩、黑云母花岗伟晶岩,通过岩石浸泡试验,发现各类岩石中的铀都可被水浸出,浸泡液的铀浓度与岩石铀含量、浸泡时间成正相关关系。研究表明特定区域水体中的铀浓度主要取决于该区域地质体中的铀含量和其水浸出性能,研究结果为该矿床辐射环境治理提供了依据。

Biotite plagioclase gneiss and biotite granitic pegmatite are mainly exposed in a uranium deposit.It is found that uranium can be leached from the three kinds of rocks through the immersion test.Uranium concentration of the soaking solution is positively correlated with uranium content in rocks and immersion time.Therefore,It is concluded that the uranium background concentration of water in a specific area mainly depends on the uranium content in geological body and the leaching performance.The results provide a basis for radiation environment control of the deposit.
