Process for extracting lithium from seawater may be better suited for salt water from continental sources – Roskill



However, Roskill points out that the membrane used in the experiment had a diameter of 2020 mm with a thickness of 5555 μm and was reported to be particularly brittle. This means that upscaling of the thin membrane, which is critical for process yields, can create a barrier to commercial scale operations.

In addition to this, the analyst highlights the fact that the sample of seawater used from the famous saltwater Red Sea will not be representative of water from many other seas and oceans.

Despite these observations, Roskill says that the method of producing lithium phosphate from brine with brine containing 0.9% Li could have other uses.

“While seawater represents a potential new lithium source, the process may increase the use for purification and upgrading of higher concentrations of lithium salt water derived from continental or geothermal sources,”

; the review said. “The ability to produce high purity lithium phosphate with low Mg, Na and other impurities would make products from multiple saltwater sources viable for use in Li-ion battery applications and could reduce the need to upgrade lithium compounds using existing expensive processes.”
