Exxon last year announced plans to extract lithium from the Smackover Formation, an underground deposit of salty water known as brine that stretches from Florida through Arkansas and into Texas ...
Such lithium enrichment is responsible for all commercially promising lithium ore deposits. Brines (and dry salt) are another important source of Li +. Although the number of known lithium-containing deposits and brines is large, most of them are either small or have too low Li + concentrations. Thus, only a few appear to be of commercial value.
Exxon Mobil on Monday announced it's drilling for lithium in southern Arkansas, with the oil giant expected to begin production of the critical material for electric vehicles by 2027. Exxon in ...
