Sociedad Química y Minera de Chile (SQM) is a Chilean chemical company and a supplier of plant nutrients, iodine, lithium and industrial chemicals. It is the world's biggest lithium producer. [2] SQM's natural resources and its main production facilities are located in the Atacama Desert in Tarapacá and Antofagasta regions.
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 ...
The extraction of lithium carbonate at high pressures of CO 2 and its precipitation upon depressurizing is the basis of the Quebec process. Lithium carbonate can also be purified by exploiting its diminished solubility in hot water. Thus, heating a saturated aqueous solution causes crystallization of Li 2 CO 3. [20]
Chile's millennial president, Gabriel Boric, promised to mine differently. When Boric announced his ambitious plan in April to take state control over the country's lithium industry and expand ...
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]
SANTIAGO (Reuters) -A protest by several hundred people in northern Chile on Wednesday blocked access to the Atacama salt flat, the world's largest lithium deposit, where domestic producer SQM and ...
