International Classification:

C01D 1500

US Classification:

4231795, 423277, 423332, 423395, 423400, 423463, 423464, 423518, 4235192, 423515, 423551, 4235662, 423605, 423606, 423641, 423642, 423643, 423646, 562477, 562493, 562578, 562582, 562584, 562588, 562607, 562609

Abstract:

The present invention provides an inexpensive process for the preparation of lithium salts of formula LiX having a desired or required level of purity using lithium chloride and lithium sulfate. In the process of the invention, a lithium salt selected from lithium chloride, lithium sulfate, and combinations thereof is reacted with NaX or KX in a aqueous, semiaqueous, or organic solution and the precipitated salts are removed to obtain the LiX solution of desired purity. Preferably, a semiaqueous solution containing water and an organic solvent is used at some point in the reaction. The process of the invention eliminates the use of highly acidic materials and thus reduces the cost of raw materials and the need for specialized equipment.

Appl. No.:

13/288389

Inventors:

Pablo Alurralde - Salta, AR
Vijay Mehta - Gastonia NC, US

Assignee:

FMC Corporation - Philadelphia PA

International Classification:

C01D 15/00

US Classification:

4231795, 252184, 23295 S, 23306

Abstract:

The present invention provides a process for recovering Li values from a sodium saturated brine. The process includes recovering Li values from a sodium saturated brine which contains LiX. The process includes concentrating the sodium saturated brine to at least 9000 mg/l LiX, passing the concentrated brine through a bed of polycrystalline hydrated alumina pellets until the pellets are loaded with LiX from the concentrated brine, displacing brine held-up in the bed by using concentrated NaX, unloading LiX from the pellets by flowing through the bed an aqueous solution of LiX which is not saturated, displacing the LiX from the bed using concentrated NaX, and repeating the steps at least one additional time to provide the Li values.
