地电化学提取铀的机制探讨
|
摘要
在以地下水为导电液的地电化学提取铀的过程中,不需要另外加入氧化剂和溶浸剂即可对铀进行浸出。比较浸出渣与原矿中的U(Ⅳ)与U(Ⅵ)质量分数,发现地电化学提取铀的过程中自身具有氧化作用,但是这种氧化作用不同于电化学电解氧化,也不同于化学氧化剂的氧化。试验发现,地电化学提取铀的过程与地磁场具有密切关系,进而推测:地电化学提取铀过程中的氧化作用是一种新的氧化作用——电磁辐射驱电子的物理氧化作用。变化的地磁场在地电化学浸出装置与含矿含水层之间形成闭合的导体回路中产生新的电磁辐射,从而实现"电磁辐射驱电子"——四价铀的氧化。地电化学提取铀的实质在于地磁能的利用。
The test results show that the extracting uranium does not need oxidant and lixiviant by means of geoelectric chemistry extracting uranium process in which ground water is used as a conducting solution.The oxidation is found in this process by analyzing the results of U(Ⅳ)/U(Ⅵ) in the ore and residue.This oxidation mechanism is different from electrolytic oxidation and chemical oxidation.This new oxidation mechanism is that the electromagnetic radiation drives out the electron of uranium atom.The electromagnetic radiation is produced by the changed magnetic field of the geomagne-tic field in the closed circuit cycle which is constructed with geoelectric chemistry extracting devices and ore bearing aquifer.So the essence of geoelectric chemistry extracting uranium process is the utilization of geomagnetic energy.
