It's a good thing POSCO's POSLx uses less water ( by how much I don't know, but I presume a lot less water ) and SDV is in Argentina and not Chile:

While traditional lithium extraction takes anywhere from 12-18 months, POSCO’s new method shortens the time frame to anywhere from eight hours to one month while also offering a purity rate of 99.9% and increasing the lithium recovery rate to over 80%. Also, typical brine extraction by evaporation is a resource heavy process, and POSCO’s advancements help to make it a much more sustainable venture, using less water and resources.
