Separation and purification by ion exchange resin, France
IX separation (or Ion Exchange) is a process for effectively removing a metal from an aqueous solution, even when present in trace amounts.
The purpose of ion exchange resins is to selectively fix the target element and concentrate it in an eluate to precipitate it.
CIME has several technologies, adaptable to the metal to be recovered, present in different matrices (H2SO4, HNO3 ...). For example, it has developed customized resins for the extraction of uranium from phosphates. The extraction of traces of heavy metals like cadmium, sometimes present in the phosphoric matrix, has also been studied.
