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] The brine contains many different dissolved ions, and as the concentration increases, salts precipitate out of solution and sink.
The lithium extraction process in Salar de Atacama begins with salty brine being pumped out of the ground and then put to rest in evaporation ponds so the remaining brine is slowly enriched in lithium. The evaporation pond stage takes usually 12 to 18 months which is the time it takes for it to reach a lithium concentration of 6%. [24]
Lithium carbonate is an important industrial chemical. Its main use is as a precursor to compounds used in lithium-ion batteries. Glasses derived from lithium carbonate are useful in ovenware. Lithium carbonate is a common ingredient in both low-fire and high-fire ceramic glaze. It forms low-melting fluxes with silica and other materials.
SANTIAGO (Reuters) - 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 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.
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 Lithium Triangle (Spanish: Triángulo del Litio) is a region of the Andes that is rich in lithium reserves, encompassed by the borders of Argentina, Bolivia, and Chile. [1] The lithium in the triangle is concentrated in various salt pans that exist along the Atacama Desert and neighboring arid areas .
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 ...
