Influence of the evaporation rate over lithium recovery from brines
(WJRR, 2016-07)
The brines of the South American Puna contain a great amount of valuables ions. Among them, lithium has the highest economic value; therefore, its grade and recovery are of interest in the purification steps of the brine. ...
Saharan lithium: Brine chemistry of chotts from eastern Algeria
(Pergamon-Elsevier Science Ltd, 2020-04)
Salt pan brines in desert areas are globally known to be rich sources of lithium. This study reports the results of a regional survey of brine chemistry in chotts (salt pans) conducted along a 550 km long valley in the ...
Potential water recovery during lithium mining from high salinity brines
(Elsevier, 2020-02)
Lithium extraction from continental brines involves the evaporation of large amounts of water in open air ponds, in order to concentrate the brine. The evaporitic technology implies the evaporation of large water volumes, ...
Membrane electrolysis for the removal of Mg2+ and Ca2+ from lithium rich brines
(Pergamon-Elsevier Science Ltd, 2019-05)
Lithium is today an essential raw material for renewable energy technologies and electric mobility. Continental brines as present in the Lithium Triangle are the most abundant and the easiest to exploit lithium sources. ...
Performance of a double-slope solar still for the concentration of lithium rich brines with concomitant fresh water recovery
(Elsevier, 2021-10-15)
Lithium recovery from brines has become a hot topic. The current evaporitic technology is slow, and serious environmental concern has been raised regarding the large volumes of water used, relating both to brine concentration ...
Lithium and boron in calcified tissues of vicuna and its relation to the chronic exposure by water ingestion in the Andean lithium triangle
(Society of Environmental Toxicology and Chemistry, 2019-12)
Vicuna is a wild, endangered species of Andean camelid living in the hyperarid Andean plateau. In the central part of the plateau, the Lithium Triangle defines a zone with lithium‐rich salt pans. Brine pools naturally form ...
The role of climate in the accumulation of lithium-rich brine in the Central Andes
(Elsevier, 2013-09)
Lithium-rich brine within the sub-surface of the Salar del Hombre Muerto (SHM) salt pan in the Andes of northwestern Argentina has a chemical and isotopic composition which is consistent with Li derived from several sources: ...
Boron extraction using selective ion exchange resins enables effective magnesium recovery from lithium rich brines with minimal lithium loss
(Elsevier Science, 2021-11-15)
Magnesium hydroxide is a commodity chemical, produced in almost pure form from seawater through precipitation. Even though Li brines contain high concentrations of Mg2+ cations, the precipitation of Mg(OH)2 from them is ...
Brine grades in Andean salars: when basin size matters A review of the Lithium Triangle
(Elsevier Science, 2021-06)
The Lithium Triangle, a zone of the Central Andes characterized by the presence of lithium (Li)-rich salt pans within endorheic basins, has gained a worldwide reputation chiefly due to its exceptional Li brine-type deposits. ...
Chemical and isotopic features of Li-rich brines from the Salar de Olaroz, Central Andes of NW Argentina
(Pergamon-Elsevier Science Ltd, 2020-11)
The lithium-rich brines of the Salar de Olaroz in the Central Andes of NW Argentina are considered to be of great economic and strategic interest. This study focused on the fluid source(s) and geochemical processes governing ...
