Abstract

The recovery of uranium and other valuable metals from Polish Peribaltic sandstones were examined. The solid-liquid extraction is the first stage of the technology of uranium production and it is crucial for the next stages of processing. In the laboratory experiments uranium was leached with efficiencies 71-100 % by acidic lixiviants. Satisfactory results were obtained for the alkaline leaching process. Almost 100 % of uranium was leached with alkaline carbonate solution. In post leaching solutions only uranium and small amounts of vanadium were present.

摘要

对从波兰波罗的海沿岸砂岩中回收铀和其他贵重金属进行了研究。固液萃取是铀生产技术的第一阶段，对后续加工阶段至关重要。在实验室实验中，酸性浸出剂对铀的浸出效率为71%至100%。碱性浸出过程取得了令人满意的结果。用碱性碳酸盐溶液几乎可将100%的铀浸出。浸出后的溶液中仅含有铀和少量钒。
