Abstract
The present invention relates to the extraction of lithium from liquid resources such as natural and synthetic brines, leachate solutions from clays and minerals, and recycled products with the assistance of an alternate phase.
Claims17
A process for extracting lithium from a liquid resource comprising:
- a) contacting a lithium selective sorbent with the liquid resource, wherein the liquid resource comprises lithium ions, and wherein lithium ions in the liquid resource are at least partially absorbed by the lithium selective sorbent to yield an enriched lithium selective sorbent;
- b) contacting said enriched lithium selective sorbent with an eluent such that lithium is at least partially eluted from said enriched lithium selective sorbent to yield an enriched eluate and the lithium selective sorbent;
- and
- c) contacting an alternate phase with said lithium selective sorbent, said enriched lithium selective sorbent, said liquid resource, said eluent, said enriched eluate, or any combination thereof, wherein the alternate phase is a non-aqueous liquid or a gas.
