During this process, a slurry of "slaked" hydrated lime, Ca(OH)2, is added to the brine to remove other elements, like magnesium and boron (which have uses in the energy transition.) Finally, once the lithium concentration reaches a certain purity, the brine is pumped to a recovery facility to extract the metal.Web
