摘要
通过50天的静态浸泡实验,模拟深层埋藏的尾矿和地下水层静态处于共存状态下,探究尾矿中铀和硫酸根离子的释放过程,以及粒径对铀尾矿中主要污染物的浸出过程、浸出速率和浸出稳定性的影响。实验结果表明:粒径对尾矿中主要污染物的浸出速率影响较大;粒径对铀尾矿中铀元素浸出过程稳定性具有一定的作用;硫酸根离子溶出的过程和稳定性都没有明显受到粒径的影响。
By 50 days the static immersion test, simulated deep burial of the tailings and aquifers, static in the coexistence state and release to explore the process of railings of uranium and sulfate ions, and particle size on leaching process of uranium railings of major pollutants, leaching rate and leaching stability.The experimental results show that the particle size on the leaching rate of railings of major pollutants in greater impact;particle size of uranium tailings of uranium leaching process stability has a role;sulfate ion stripping process and stability are not obviously by the influence of the particle size.
