1. A method of recovering lithium from a lithium source, comprising:
concentrating an aqueous lithium source in a feed preparation stage to yield an aqueous extraction feed having an extraction lithium concentration; and extracting lithium from the aqueous extraction feed, or a derivative thereof, using direct lithium extraction in an extraction stage to yield a lithium intermediate, wherein concentrating the aqueous lithium source comprises at least a membrane separation operation.
