Description

Technical field

[0001] The invention relates to the technical field of ion exchange, in particular to an ion exchange tower for uranium hydrometallurgy. Background technique

[0002] The device in which the ion exchange reaction occurs in the uranium hydrometallurgical process is called an ion exchange tower, which is used to separate and extract uranium from the leaching liquid of uranium ore. The currently used uranium hydrometallurgical ion exchange tower is attached Figure 7 As shown, it includes a tower body 5 and a filter plate filter device 6. The filter plate filter device 6 is installed at the bottom of the tower body 5. Quartz sand 7 is stacked on the filter plate filter device 6, and the leachate is filtered through the quartz sand 7. The latter leachate flows out from the filter plate filter device 6. Existing uranium hydrometallurgical ion exchange towers have the following problems: one is that the opening rate of the filter plate is low, and the amount of water pa...
