Abstract
The invention provides a process for improving the leaching of uranium-molybdenum ore and the separation of uranium and molybdenum. The steps are as follows: (1) performing two-stage countercurrent enhanced acid leaching on uranium-molybdenum ore; (2) performing two-stage countercurrent enhanced acid leaching on low-uranium molybdenum ore Acid leaching: (3) Mix the uranium-molybdenum ore leachate and the low-uranium molybdenum ore leachate in a volume ratio of 1: (1 to 8), add potassium permanganate or pyrolusite to the resulting mixture, and adjust the potential to more than 500mv; Regulate the acidity so that the concentration of H+ ions in the mixed solution is 0.25 to 16mol / L; (4) the mixed solution obtained after adjusting the potential and acidity in step (3) is the extraction stock solution to extract molybdenum; (5) to step (4) Extract the molybdenum obtained organic phase to back-extract the molybdenum, and finally obtain the qualified molybdenum liquid; (6) extract uranium from the raffinate water obtained by extracting the molybdenum in step (4); (7) extract the organic phase obtained after the step (6) extracts the uranium. The uranium is back-extracted, and finally the uranium qualified liquid is obtained. The invention has high resource utilization rate, good separation effect of uranium and molybdenum, and low comprehensive extraction cost.
Description
A process method for improving uranium-molybdenum ore leaching rate and uranium-molybdenum separation Technical field The present invention relates to the hydrometallurgical process that uranium-molybdenum ore comprehensively reclaims uranium-molybdenum, specifically belongs to a kind of improving uranium-molybdenum ore leaching Yield and uranium molybdenum separation process. Background technique In the surveyed uranium resources of China, there are considerable proportion of associated and paragenetic uranium deposits, according to preliminary investigation, wherein molybdenum-containing Uranium resources account for a relatively large proportion. At this stage, there are usually the following methods for the treatment of uranium-molybdenum ore and low-uranium-molybdenum ore: Conventional alkali leaching and conventional acid leaching, leaching after roasting and pressurized alkali leaching, etc.; the separation of uranium and molybdenum generally needs to be carried ...
