Description

Method for concentrating a substance containing uranium and calcium in solution, whereby the solution is passed through a first separation system containing at least one semi-permeable membrane capable of concentrating the uranium, in order to concentrate it and allow through a significant portion of the solution to provide a current of uranium concentrate and a uranium-free current containing cations, anions and impurities of low molecular weight
