Abstract
The present invention is a composition comprising pellets, each of said pellets consisting essentially of an integral mass of polycrystalline material of randomly disposed crystals of hydrated alumina infused with an amount of LiX to produce LiX/Al(OH)3 having up to a mol fraction of 0.33 of LiX in the so-produced LiX/Al(OH)3, wherein LiX is at least one compound selected from the group consisting of Li hydroxide, Li halide, Li nitrate, Li sulfate, and Li bicarbonate. The present invention further includes methods of preparing the composition and methods of recovery lithium values from brine using the composition.
