Purolite ion-exchange resins in technologies for extracting and purifying valuable components from solutions
Ion exchange is widely used in technologies for extracting valuable components from solutions due to its well-known advantages: large depth of purification, compactness of installations, ease of operation and the possibility of full automation of their work, resistance to concentration and hydraulic flow fluctuations. In metallurgy, the introduction of ion-exchange technologies has opened up access to the efficient processing of low-grade ores, previously considered waste rock.
The presentation gives examples of existing ion-exchange technologies: purification of a cobalt chloride solution from cadmium, purification of a copper electrolyte from antimony and tin, purification of a solution of rare earth elements (REE) from uranium and thorium, extraction of lithium and purification of lithium salt solutions from impurities.
Purolite is committed to partnering with interested parties to develop and improve technologies for extracting valuable components from solutions.
