Hypocrisy at its finestSo oil companies found high concentrations of lithium in the brine waste water after fracking in the shale areas. This salty waste is actually full of lithium. Enter Exxon with DLE (direct lithium extraction) shoot water into the ground with some additives and remove lithium from the salty highly contaminated water (also full of lead and arsenic) BUT no way is it called fracking. LMAO. This is the big "technological" way to remove it from the clays of Sonora. Not with geologists but with oil people. Mining is extraction. Any given extraction wether above below or fracked requires an analysis of the geology and environmental / water structures. This has been done with great success in recent years. To generically say an underground mine is "always" more human & environmentally safe is simply false.
