“Extraction of lithium from geothermal brines is expected to be particularly challenging,” the lab explains. “The brine is extremely hot when it comes out of the subsurface, and it contains a rich stew of many dissolved minerals in addition to lithium.”
To visualize how complex and delicate the extraction process is, imagine you are flipping for baseball cards, except all of your cards are stuck together and they are on fire.

Still, it's very tempting to try to get at this ready source of lithium with a power source at hand as well. At this time, lithium is needed for electric vehicles for their batteries.
