Process: Separation by Ion Exchange Resins
<p>Access a selective and cost-effective process that enables you to separate and purify your metals, even at trace levels.</p>
-
- Improve the purity of your metals with a hydrometallurgical process.
- Eliminate impurities present in your leach solutions.
- Recover and valorize strategic metals, including from by-products.
- Reduce processing costs by replacing or complementing complex chemical steps.
- Rely on a process adaptable to different metals and concentration ranges.
-
- Implement a process based on ion-exchange resins that ensures selective and efficient metal separation.
- Purify your leach solutions by eliminating undesirable elements that degrade metal quality.
- Recover your target metals, even at trace levels.
- Easily adapt the process to your needs thanks to three mastered IX technologies (RIP, fixed bed, CIX).
- Optimize your processes using resins composed of fine particles that allow rapid exchanges and short equilibrium times.
-
- Three IX technologies operated at CIME: RIP, fixed bed, CIX.
- Wide concentration range treated: from a few mg/L up to 500 mg/L.
- Flexible operation: from 100 mL/h to several L/h.
- High-performance resins: fine particles for fast exchanges and short equilibrium times.
- International experience: R&D trials and column sizing for the uranium plant in Kazakhstan and an industrial pilot in Mongolia.
- Valorization of uranium recovered as a by-product from phosphates or sulfate/chloride effluents.
- Recovery and valorization of strategic elements: rhenium, molybdenum, gold, uranium.
- Wide applications: water treatment, decontamination of radioactive effluents, extraction of heavy metals (cadmium, chromium), fixation of ²²⁸Ra and production of ²¹²Pb.
- Mastery of IX process development steps: batch tests (isotherms, continuous columns) followed by pilot-scale trials.
- Development of new resins tailored to specific needs.
