The World’s largest lithium reserves and large parts of the total production are located in the Salar de Atacama. Lithium extraction in Bolivia, Argentina, and Chile requires significant amounts of water, at approximately 500,000 gallons per ton of lithium. This production site in Chile is located at the Salar de Atacama, one of the driest deserts on earth. Albemarle Corp, the world’s largest lithium producer, has accused its top rival, Chilean miner SQM, and local regulators of seeking to keep secret a … It is second in grade only to the Salar de Atacama, which accounts for 100% of Chile’s lithium production and about 40% of global production. o Lithium brine is found in salt flats such as the salt flats in Salar de Atacama, or the Atacama Desert, the driest desert on Earth. Since 1980, two companies have been mining lithium in the Salar de Atacama, Chile’s largest salt flat, which holds a third of the world’s reserves of the mineral. The Salar de Atacama is host to more than 15% of the world’s known lithium reserves, and yet exploration and production of lithium has occurred only in the southern portion of the Salar. Recent estimates show that the lithium resources known exceed 40 million tons of Li, corresponding to more than 210 million tons of lithium carbonate equivalents. The proprietor of the claims in the Salar de Atacama nucleus is the state owned Corporación de Fomento de la Producción (CORFO). Strain LCHXa is a novel free-living Gram-positive, non-motile bacterium strain isolated from water samples taken at Laguna Chaxa, a non-industrial water body with the highest soluble Li content (33 mM LiCl) within the Salar de Atacama basin in northern Chile. DIFFERENCE BETWEEN WATER AND BRINE Beneath the salt coating of the Salar de Atacama is a large deposit of a saline solution with a water content of approximately 70%, the so-called brine. To get sufficient concentration of lithium, the brine is pumped into evaporation ponds and then goes through repeated cycles of solar evaporation. In Chile’s Salar de Atacama, lithium extraction being performed by various companies has consumed Acquisition and exploration began in April 2016. Parts of the Atacama Desert have gone without rain for as long as people have been keeping track, but water rich in dissolved salts lies beneath this flat surface. Lithium is an essential component of advanced batteries and medicines. The subsurface brines of the Salar de Atacama are particularly rich in lithium salts. The world’s largest lithium reserve is located in the Salar de Atacama, in Chile. The proximity of the Project to existing producers strongly suggests that exploration potential is good for the discovery of brines in the northern portion of the Salar, underlying the Project. Enrichment was conducted in Luria-Bertani (LB) medium supplemented with 1 M LiCl. Indeed, since 1984, some 100,000 tons of Li have been extracted from this location (Tahil, 2008). The brines are pumped to the surface through a network of wells and into large, shallow evaporation ponds; three such evaporation facilities are visible in the center of the image. The Li-rich brine contained within the halite body of the Salar de Atacama is uncommon for two reasons: First, it has an exceptionally high Li concentration, even compared to other closed basins in the Li triangle of South America; and second, it is widespread within the halite nucleus and not restricted to … A truck on its way through Chile's Salar de Atacama. Lithium Mining in Chile. The saltworks of Rockwood Lithium GmbH (), the subject of the present study, are located in the S part of the Salar de Atacama, near the Península de Chépica approximately 80 km from San Pedro de Atacama and 25 km from Peine. "We think that SQM should be re-nationalized and the state should take on responsibility for lithium extraction," Soto told DW, pointing to lithium’s potential application in nuclear weapons and objections from indigenous people in the Atacama Desert. "Over-exploitation of the Salar de Atacama could cause an environmental catastrophe," he added. FILE PHOTO: Brine pools from a lithium mine, that belongs U.S.-based Albemarle Corp, is seen on the Atacama salt flat in the Atacama desert, Chile, August 16, 2018. In the Salar de Atacama salt flat, lithium exists as a mineral salt suspended in underground reservoirs of brine. Lithium Chile's exploration portfolios currently comprises 152,900 hectares in seventeen properties. Lithium is extracted from brine deposits in Salar de Atacama PUMPING Lithium-rich brine, or saltwater, is pumped from depths of 1.5 to 60 meters below surface via wells scattered across Salar. Three large (20-25 km2) TEM anomalies within 30 – 150m of surface and 80-110m thick. Maricunga Lithium Project. The principal origin of lithium in the Salar de Atacama is interpreted to be the lithium-bearing geothermal waters from the El Tatio Geyser Field, located north of the salar. The geothermal fluids enter the northern part of the Salar de Atacama via surface and subsurface flow. Further, the chemistry of the salar brines is almost identical to ... SQM and Albemarle have rental contracts there with the Corporación de Fomento de la Producción (CORFO), Chile’s agency in charge of supporting entrepreneurship, innovation and competitiveness. The upper halite layer with a thickness of 55m hosts the highest brine concentration. world, the Salar de Atacama is considered to represent the planet’s largest deposit of economically recover-able Li (Tahil, 2008), even though the Salar de Uyuni actually contains a larger amount of Li. The western and lower alluvium layers and the upper and the lower volcaniclastic layers also host significant mineralization. The country has 48% of the total lithium reserves in the world which amounts to 7.5 million tonnes of lithium, of which 6 million tonnes is found in Salar de Atacama. Meanwhile, in Salar del Carmen, in Antofagasta, the process residues are magnesium and carbonate salts, which are … Potash, for the manufacture of fertilisers, is also recovered at the Salar. The global automotive industry needs batteries for the transition to electric driving, and lithium is key to that. There are aspects to the situation that are logistical, political, economic, environmental, and commercial, but there is one central feature of the “drama in the Atacama” which is technical. Evaporation techniques are commonly utilized to extract lithium. Salar de Atacama is rich in lithium, essential to electric cars and other low-carbon tech. 75 flora registration plots, distributed in 7 transects along the eastern edge of the Salar de Atacama. 1. The Salar del Hombre Muerto is Chile's largest salt flat holds a third of the world's reserves of the mineral. Hydrological issues associated with brine extraction to produce potash and lithium at the Salar de Atacama in Northern Chile are complex, but often over-simplified as “water unavailability”. The region’s ecosystem is fragile and there is lack of consensus regarding the impacts and risks of lithium mining and other economic activity in the region. Lithium-rich brines that are produced in the north part of the Salar de Atacama flow from north to south across the Atacama Lithium Project. The surrounding conditions are ideal for the production of lithium carbonate on the basis of natural brines from the Salar. They are based on a long-term contract with the Chilean government, which was originally entered into in 1975 by one of the company’s predecessors. SQM operates here, lithium is obtained from brine in a sustainable process. The silver-white metal is found dissolved in brine, a mere 130 feet below the surface of the desert. Near-surface brine samples assaying up to 1330 mg/l lithium – comparable to SQM and Albemarle’s production plants. Excellent chemistry; Li:K ratio 0.09, Mg:Li ratio 2.6. Three large (20-25 km2) TEM anomalies within 30 – 150m of surface and 80-110m thick. The clay core below the upper halite layer extends to a depth of 170m. Lithium Mining in Chile. Salar de Atacama, Chile. Salar de Atacama, located 55 km (34 mi) south of San Pedro de Atacama, is the largest salt flat in Chile. Sustained production of lithium, potassium and yproducts has occurred in the b Salar since the 1970’s from properties contiguous to the Atacama Lithium … Near-surface brine samples assaying up to 1330 mg/l lithium – comparable to SQM and Albemarle’s production plants. The percentage of salt is relatively high with 300.000 mg / l with … In the wastelands of Salar de Atacama, about 700 miles north of Santiago, is a huge lithium mine field operated by Sociedad Química y Minera de Chile (SQM), a Chilean chemical company, and the world’s third largest produced of lithium. ABOUT THIS ASSET. Part of the famed lithium triangle, Argentina produced 6,400 tonnes of the metal in 2019, taking fourth place on the list of the world’s top-producing countries. The pools are left up to eighteen months so the liquid can evaporate. The variables that make up the biotic monitoring in the Salar de Atacama are: Vegetation with 99 monitoring points on the eastern edge of the Salar de Atacama. 18 fauna sampling stations (avifauna, mammals, reptiles). The lithium extraction process in the Salar de Atacama means that the impurities, which are returned to the Salar, are the same elements that were already in the basin. Miners drill into salt flats and pump salty lithium brine water to the surface. Salar de Atacama, Chile. The Salar de Uyuni, located in southeast Bolivia, is It is surrounded by mountains and has no drainage outlets. Together, the Salar de Atacama and the Salar del Hombre Muerto provide between 50-70% of the world’s lithium supply1 (Mercado & Cordova 2015, p. 8), (ABC Del Litio Sudamericano, F. Nacif 2018).
