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

THE PROCESS HDS processing is a proven technology that has been in use in the mining industry for since the 1980s. The process begins by mixing incoming effluent with a neutralizing agent (limestone/lime) and recycled sludge from a clarifier/ thickener unit. After neutralization, this mixture is fed to the main lime reactorWeb
