在净化处理铀生产厂和加工厂的废水时,通常必须从大量的水溶液中分离回收少量的铀(浓度≤100毫克/升)。曾报道过,有可能采用浮选法,从含铀稀溶液中以混合的亚铁氰化铀酰的形式回收铀。下面将介绍一些实验结果,其目的是研究用脂肪族伯胺(ПAA)及 AHП-2从碳酸盐溶液中浮选回收铀的规律性。实验所用伯胺的烷基链含有8—18个碳原子。AHП-2系脂肪族
In the decontamination of wastewater from uranium plants and processing plants, it is usually necessary to separate and recover small amounts of uranium (concentrations ≤100 mg / l) from large volumes of aqueous solution. It has been reported that it is possible to use flotation to recover uranium from mixed uranium ferrocyanide in dilute uranium solution. A few experimental results are presented below to investigate the regularity of flotation recovery of uranium from carbonate solutions using aliphatic primary amines (ΠΑΑ) and AHП-2. The primary amine used in the experiment had 8-18 carbon atoms in the alkyl chain. AHП-2 is aliphatic
