“…The second step employed a 1 M mixture of Aliquat-336 and DEHPA to remove 83% of the dissolved lithium in one cycle. This result was reported to be superior to other methods using other extractant combinations [221].…”

“…In this study, diethyl succinate was used as a diluent, TBP acted as the extractant, and FeCl3 was the co-extractant. The highest onestage extraction efficiency of lithium was approximately 65%, with a maximum separation Zante et al [221] investigated the extraction of lithium from brines using the ionic liquid methyltrioctylammonium chloride (Aliquat-336) and the extractant DEHPA (Figure 18), dissolved in n-dodecane. These investigators targeted the extraction of lithium from produced waters from oil and gas wells and selected these reagents due to their commercial availability and relatively lower costs [221].…”

Lithium is the principal component of high-energy-density batteries and is a critical material necessary for the economy and security of the United States. Brines from geothermal power production have been identified as a potential domestic source of lithium; however, lithium-rich geothermal brines are characterized by complex chemistry, high salinity, and high temperatures, which pose unique challenges for economic lithium extraction. The purpose of this paper is to examine and analyze direct lithium extraction technology in the context of developing sustainable lithium production from geothermal brines. In this paper, we are focused on the challenges of applying direct lithium extraction technology to geothermal brines; however, applications to other brines (such as coproduced brines from oil wells) are considered. The most technologically advanced approach for direct lithium extraction from geothermal brines is adsorption of lithium using inorganic sorbents. Other separation processes include extraction using solvents, sorption on organic resin and polymer materials, chemical precipitation, and membrane-dependent processes. The Salton Sea geothermal field in California has been identified as the most significant lithium brine resource in the US and past and present efforts to extract lithium and other minerals from Salton Sea brines were evaluated. Extraction of lithium with inorganic molecular sieve ion-exchange sorbents appears to offer the most immediate pathway for the development of economic lithium extraction and recovery from Salton Sea brines. Other promising technologies are still in early development, but may one day offer a second generation of methods for direct, selective lithium extraction. Initial studies have demonstrated that lithium extraction and recovery from geothermal brines are technically feasible, but challenges still remain in developing an economically and environmentally sustainable process at scale.

“…In the first stage, divalent metals are removed from the repeated extraction cycles using DEHPA (1 mol/L) dissolved in dodecane. Step two included the use of the ionic liquid extracting agent [Aliquat-336] [DEHPA] to remove 83% of Li in a single extraction cycle, which is better than the results of solvent extraction with conventional extracting molecules [14]. In contrast, there are limitations to using solvent extraction methods in the real world, such as the solution's acidity, equipment corrosion, increased chloride ion levels, and complicated operating setups [91].…”

The global demand for lithium, which is indispensable for electric cars and electrical devices, has increased. Lithium recovery from oilfield-produced water is necessary to meet the growing need for lithium-ion batteries, protect the environment, optimize resource utilization, and cut costs to ensure a successful energy transition. It is useful for keeping water supplies in good condition, adhering to legal requirements, and making the most of technological advances. Oil and gas companies might see an increase in revenue gained through the lithium extraction from generated water due to the recouping of energy costs. Therefore, this review focuses on contamination and treatment strategies for the oilfield-produced water. It includes a discussion of the global lithium trade, a financial analysis of lithium extraction, and a comparison of the various methods currently in use for lithium extraction. It was evaluated that economic considerations should be given priority when selecting environmentally friendly methods for lithium recovery from oilfield-produced water, and hybrid methods, such as adsorption–precipitation systems, may show promising results in this regard. Lastly, future prospects for the lithium industry were also discussed.

Dual carbon policies have spurred rapid growth in the electric vehicle and energy storage industry, leading to a surge in demand for lithium batteries. To help meet this demand sustainably, the natural polymer sodium alginate (SA) was cross-linked with Ca 2+ , and the SA/hydrogen manganese oxide (HMO) composite granular adsorbent was successfully prepared by the crosslinking method. The aim is to extract lithium from shale gas wastewater in the Sichuan Basin, China. The produced microporous composite granular adsorbents have an average pore size of 20 nm and excellent hydrophilicity, with a swelling ratio of roughly 15 g/ g at a mass concentration of 3.5 wt % alginate and 2 wt % HMO. When deployed with real wastewater, this material achieved a lithium adsorption capacity of 4.3 mg/g. In laboratory-scale fixed-bed filtration experiments, the optimal adsorbent material was saturated after approximately 700 min at an approach velocity (hydraulic load) of 0.47 cm/min and using a total bed volume of 15 cm 3 containing approximately 0.55 g of adsorbent. In the subsequent recovery step of the adsorbed lithium through desorption, a lithium solution with a concentration of 113 mg/L was achieved. The results suggest that this novel composite granular adsorbent has promising adsorption capacity and that optimization of adsorption and desorption cycles and engineering of the separation system deploying this material would allow high-efficiency lithium adsorption.
