  • Process for recovery of lithium from brine
    Patent number: 11583830
    Abstract: 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 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.
    Type: Grant
    Filed: June 8, 2020
    Date of Patent: February 21, 2023
    Assignee: STANDARD LITHIUM LTD.
    Inventor: Craig Johnstone Brown
