Recovery of lithium values from brines |
摘要 |
Morphologically altered pellets of a polycrystalline hydrated alumina, intercalated with LiX (where LiX is a lithium salt, preferably LiCl), is prepared by contacting the polycrystalline structure with LiX solution carried in NaCl brine, the LiX creating lithium-specific sites of intercalation in the crystalline structure, and the material is used in a LiX absorption process involving unloading LiX from the pellets, and then passing a LiX-containing brine through the pellets to capture more LiX in the Li-depleted active sites, and repeating the unloading and loading of the LiX a plurality of cycles. The unloaded LiX is collected as crude product which can be concentrated by evaporation and removing precipitated NaCl.
