Process: Separation by ion exchange resins
A unique, efficient and economical solution for metal separation and purification using ion exchange resins
-
Hydrometallurgy brings together all the techniques allowing the extraction of metals. It consists of a succession of chemical operations characterised by a metal in solution. However, processes such as leaching are seldom selective and the resulting solution contains other elements that may disrupt the production of the desired metal or degrade its purity. Extracting these elements is therefore necessary.
-
CIME has implemented processes from ion exchange resins for metal purification. These ion exchange resins are porous balls of polymers through which leaching solutions can circulate. They then exchange the ions on their surface with other ions provided by these solutions. The target ion or metal will therefore be removed efficiently and selectively even in trace amounts.
- Can be applied to many fields such as water treatment, effluent cleaning to eliminate its radioactivity or extract the heavy metals present (cadmium, chromium, etc.)
- Recovery of elements of interest for the mining industry (gold, uranium, etc.)
- Development of new resins adapted to your needs
- Can be applied to many fields such as water treatment, effluent cleaning to eliminate its radioactivity or extract the heavy metals present (cadmium, chromium, etc.)
-
- 3 IX Technologies piloted at CIME (RIP, Fixed Bed, CIX)
- Application over a wide concentration range (a few mg/L to 500 mg/L)
- Can be controlled from a hundred mL/hour to a few L/hour
- Resins composed of fine particles allowing rapid exchange and a low equilibrium time.
