The Li + concentration of naturally occurring salt lake brines is too low for cost-effective extraction without a pre-enrichment process (Vikström et al., 2013; Flexer et al., 2018). Consequently, solar energy is used to evaporate, and therefore, concentrate the Li + in the brine after it is pumped from the salt lake into large evaporation ponds.

In view of the frequency that chemists encounter difficult extractions, we wholeheartedly recommend expanded use of salting-out liquid−liquid extraction, particularly with salts that are consistent with green chemistry principles. At least in the context of process development, Na2SO4 has been underutilized in salting-out extractions, but we ...

Many salt mines use the "room and pillar" system of mining. Shafts are sunk down to the floor of the mine, and rooms are carefully constructed by drilling, cutting and blasting between the shafts, creating a checkerboard pattern. After the salt is removed and crushed, a conveyor belt hauls it to the surface. Most salt produced this way is used ...
