Demand to lithium rising swiftly as increasing due to its diverse applications such as rechargeable batteries, light aircraft alloys, air purification, medicine and nuclear fusion. Lithium demand is expected to triple by 2025 through the use of batteries, particularly electric vehicles. The lithium market is expected to grow from 184,000 TPA of lithium carbonate to 534,000 TPA by 2025. To ensure the growing consumption of lithium, it is necessary to increase the production of lithium from different resources. Natural lithium resources mainly associate within granite pegmatite type deposit (spodumene and petalite ores), salt lake brines, seawater and geothermal water. Among them, the reserves of lithium resource in salt lake brine, seawater and geothermal water are in 70-80% of the total, which are excellent raw materials for lithium extraction. Compared with the minerals, the extraction of lithium from water resources is promising because this aqueous lithium recovery is more abundant, more environmentally friendly and cost-effective.

“…Freundlich adsorption model, on the other hand, dealt with nonideal adsorption onto heterogeneous surfaces involving multilayer sorption. The equations of these models were as follows :

\frac{C_{e}}{{normalq}_{normale}} = \frac{1}{K_{L} q_{m}} + \frac{C_{e}}{q_{m}}

{l n q}_{normale} = l n K_{F} + \frac{1}{n} l n C_{e}

where C e (mg·L −1 ) was the equilibrium concentration of fluoride in solution, q e (mg·g −1 ) was the maximum monolayer adsorption capacity, and K L (L·mg −1 ) was the Langmuir constant, K F (L/g) and n were the Freundlich constants, indicating the adsorption capacity and the adsorption intensity, respectively.…”

Fluoride is the naturally occurring groundwater contaminant around the world, and has been the focus of extensive research efforts in the past few decades. Among various fluoride removal technologies, adsorption was the most attractive because it was highly efficient, cost‐effective, and suitable for small communities. A facile synthetic approach was presented for hierarchical flower‐like Mg–Al‐layered double hydroxides (MgAl‐LDO) via the simple hydrothermal method, followed by a subsequent calcination at 500°C for 4 h in air. The resulting calcined MgAl‐LDO were studied for their adsorption performance in removing fluoride from aqueous solutions. The results showed that the flower‐like sphere of hierarchical calcined MgAl‐LDO was synthesized by a simple hydrothermal method using urea as precipitating agent. Batch adsorption experiments demonstrated that the kinetic adsorption could be described by a pseudo‐second‐order model very well. The adsorption of fluoride on MgAl‐LDO was strongly dependent on pH value. The Freundlich model fitted the adsorption isotherms of fluoride better than the Langmuir model at three different temperatures of 25, 45, and 65°C. They were demonstrated to be reusable with the efficiency of fluoride removal up to 80% at the fourth cycle. we successfully fabricated flower‐like spherical structures MgAl‐LDO by a facile hydrothermal method without any templates. It was envisioned that the synthesized samples using this facile synthetic approach were very promising for the removal of fluoride from aqueous solutions. © 2016 American Institute of Chemical Engineers Environ Prog, 2016 © 2016 American Institute of Chemical Engineers Environ Prog, 35: 1420–1429, 2016

“…To solve this challenge, several methods have been developed for extracting lithium from salt lake brines in the Qaidam Basin, including calcination [9] , adsorption [10][11][12][13][14][15][16][17][18][19] , extraction [20][21][22][23][24][25] and membrane technology [26][27][28][29][30] . The fundamental feedstock Li 2 CO 3 , typically at industrial grades ( ∼95%), is produced by these methods.…”
