Abstract (en)
[origin: WO2020124192A1] A process for recovery of lithium ions from a lithium-bearing brine includes contacting the lithium-bearing brine with a lithium ion sieve (where that LIS includes an oxide of titanium or an oxide of niobium) in a first stirred reactor to form a lithium ion complex with the lithium ion sieve, and decomplexing the lithium ion from the lithium ion sieve in a second stirred reactor to form the lithium ion sieve and an acidic lithium salt eluate. The pH in the first reactor is maintained with an alkali such as anhydrous ammonia, ammonium hydroxide, or sodium hydroxide.
