Process of extracting lithium from seawater could be suitable for brine from continental sources – Roskill



However, Roskill pointed out that the membrane used in the experiment was ~20 mm in diameter, with ~55 μm in thickness, and was reported to be particularly brittle. This means expanding the size of the thin membrane, which is important for process productivity. Can create obstacles to commercial operations

Analysts also highlighted the fact that seawater samples taken from the famous saline Red Sea It does not represent water that comes from other seas and oceans.

Despite these observations, Roskill said the method of producing lithium phosphate from seawater-derived brine containing 0.9% Li could be used for other uses.

“While seawater is a potential new source of lithium, This process could be more useful in purifying and elevating higher concentrations of lithium brine coming from continental or geothermal sources,” the review said. “The ability to produce high-purity lithium phosphate with low Mg, Na and other impurities will make products from many brine sources usable in Li-ion battery applications and potentially reduce the need. to upgrade lithium compounds using an expensive process.”
