Typical commercial lithium concentrations are between 200 and 1,400 mg/L (1.4 g/L). The largest operations are in the shallow brine beneath the Salar de Atacama dry lakebed in Chile, which as of 2015 yielded about a third of the world's supply. The brine operations are primarily for potassium; extraction of lithium as a byproduct began in 1997 ...
Chile's Atacama salt flat is sinking at a rate of 1 to 2 centimeters (0.4 to 0.8 inches) per year due to lithium brine extraction, according to a study by the University of Chile. The study used ...
There is some capacity to convert the carbonate to lithium hydroxide in Salar de Carmen. 2019 revenues from lithium were $505mio. [13] In 2021, the lithium revenues were US$936.1 million. [15] The process involves pumping up lithium rich brine from below the ground into shallow pans. Water is evaporated thanks to the strong sun and dry air. [16]

There are concerns that lithium producers are drawing too much lithium-rich brine, or saltwater, from pools beneath the Atacama, the world's driest desert. A water fight in Chile's Atacama raises ...
The new plan seeks to employ direct lithium extraction (DLE) - a technology that promises to be more sustainable by reinjecting the brine back into the ground once the mineral is extracted.
Northern Chile forms part of the Lithium Triangle with substantial reserves in the form of brine. The explosive growth in electric vehicles since 2015 has triggered increased demand. Chile is the main producer of lithium from brine. [14] Until 2017, when it was surpassed by Australia, Chile was the over-all main producer of lithium. [15]
The protest underscored a serious challenge to a plan by Chile, the No. 2 lithium producer, to impose more state control over the metal needed for batteries used to power the world's growing ...
