The macroporous structure increases the available surface area and facilitates faster ion diffusion, which allows for higher throughput and better resistance to organic fouling compared to standard gel resins.
Resin should be kept in a wet state above 0°C. For long-term storage, it should be placed in a closed space or immersed in a salt water solution of 5% or higher to maintain stability.
Yes, it is highly effective in capturing and purifying metal ions from aqueous solutions produced via heap, tank, or in-situ leaching, and it complements bio-hydrometallurgical processes.
To prevent the resin pores from jamming with suspended solids, it is recommended to implement flocculation, filtration, or sand-filtration as preliminary steps.
Generally, the resin requires an alkali-water-acid-water flow path. For strict purity requirements, three full circulations are recommended before final ion kernel usage.
Absolutely. Its high exchange capacity and stability make it ideal for producing the contamination-free water required in pharmaceutical and electronics manufacturing.
