Vanadium Recovery from Stone Coal with Sunresin’s SMB Solution

Summary

This video discusses vanadium extraction from stone coal, emphasizing the ion exchange method as a promising alternative to traditional solvent extraction. The ion exchange process is more efficient, environmentally friendly, and requires less labor, offering an absorption rate of over 99%. The video highlights SunResin's innovative SMB (Simulated Moving Bed) system, which enhances automation, reduces resin consumption, and lowers both capital and operational expenses by approximately 50%. This system ensures higher concentration, energy efficiency, and stable production, making it a breakthrough in vanadium recovery technology.
