Abstract: Described herein are methods of recovering lithium from dilute lithium sources. The methods include extracting lithium from an extraction feed using direct lithium extraction in an extraction stage to yield a lithium intermediate, performing one or more concentration operations, each concentration operation concentrating an input stream to yield an output feed, wherein the input stream is obtained from the lithium intermediate and/or the extraction feed is obtained from the output feed. At least one of the concentration operations includes a membrane separation operation having a plurality of reactors in series each having a semi-permeable membrane, such as a counter-flow reverse osmosis operation. Methods may also include generating a low TDS stream as a permeate from any of the one or more concentration operations, wherein the low TDS stream is recycled or used as fresh water.

Abstract: Described herein are methods of recovering lithium from aqueous sources. The methods include extracting lithium from an aqueous lithium source using an extraction stage to yield a lithium intermediate; routing the lithium intermediate to a concentration stage to yield a lithium concentrate; and adjusting parameters of the ion withdrawal extraction stage to target a ratio of lithium ions to impurity ions in the lithium intermediate.

Abstract: Described herein are methods of recovering target ions from salt deposits. The methods include dissolving a target ion from a salt deposit to form a target solution and extracting the target ion from the target solution using a selective extraction process to yield a concentrate of the target ion which can be converted to a product.
