Low-concentration lithium recovery
Thread Content
Let’s discuss the recovery of low-concentration lithium (2-3 g/L); what methods are cost-effective and feasible, excluding evaporation concentration followed by sodium carbonate precipitation
Why isn’t anyone here to discuss it? Are there any resins with high lithium adsorption capacity and good selectivity? Those who manufacture such resins, please share your insights
Lithium can first be enriched in the form of alum
For iron removal in zinc smelting, there is iron aluminate slag; you can study that
Is the system complex or is it just the low concentration?
For such low-valent small ions, conventional adsorbents and extractants are ineffective, as high-valent ions such as calcium, magnesium, aluminum, and iron have a much stronger binding force with adsorbents and extractants. If you really want to do it, you should look for specialized design-specific extractants used for the synthesis of extractants.
I also want to learn* how lithium can be recovered at low concentrations I’m not sure if extraction is feasible?
Extract some wool and see if an ion membrane will work
