“…D2EHPA and TBP were used as extractants. This combined method resulted in a lithium extraction efficiency of 87.7% with a 50 times dilution rate of the geothermal fluid [23]. [32] classify the Indonesian geothermal system into six types, namely vapour-dominated systems, volcanic geothermal systems with magmatic steam plume surrounded by neutral-pH hot fluids, vapour layer systems with partially liquid-saturated layers on top and liquid-saturated substratum, vapour layer in the setting of a volcanic geothermal system, liquid-dominated systems with major fault zone, and liquid-dominated systems beneath a stratovolcano associated with a concealed outflow plume.…”

Lithium has become an essential metal for modern industries. Specifically, the growth of battery-based electric vehicles will demand much more lithium shortly. Many studies have been conducted to find the sources of lithium; one of them is geothermal brine. Indonesia has enormous geothermal resources; some fields have lithium content that can potentially be extracted. Various methods in the extraction process of lithium from the geothermal brine have been developed, both on laboratory and pilot projects. Conventionally, solar evaporation has been used to concentrate lithium from brine, but it takes a long time and depends on the weather. Thus, a more rapid and selective process is desired to fulfill the market demand and avoid weather constraints. This paper reviews the lithium extraction from the geothermal brine by direct extraction methods using solvent extraction, adsorption and ion exchange, membrane, and electrodialysis. The study is based on a desktop study and aims to summarize the knowledge, method, technology, and techniques of lithium extraction from geothermal brine that has already been used and to find out which extraction method is suitable for the Indonesian geothermal field. Multiple-stages solvent extraction from geothermal brine well X in Dieng performed by the authors demonstrated a lithium extraction efficiency of 94% and indicated an opportunity to be further investigated to extract lithium from the Dieng geothermal brine.

“…The methods for extracting lithium metal from salt lake brine include precipitation [14], solvent extraction [15], ion exchange [16], electrodialysis [17], and membrane separation [18]. Although precipitation is a simple method for recovering lithium from salt lake brine, the impurity ions in the brine affect the purity of lithium and its recovery efficiency [2].…”

Lithium recovery is imperative to accommodate the increase in lithium demand. Salt lake brine contains a large amount of lithium and is one of the most important sources of lithium metal. In this study, Li2CO3, MnO2, and TiO2 particles were mixed, and the precursor of a manganese–titanium mixed ion sieve (M-T-LIS) was prepared by a high-temperature solid-phase method. M-T-LISs were obtained by DL-malic acid pickling. The adsorption experiment results noted single-layer chemical adsorption and maximum lithium adsorption of 32.32 mg/g. From the Brunauer–Emmett–Teller and scanning electron microscopy results, the M-T-LIS provided adsorption sites after DL-malic acid pickling. In addition, X-ray photoelectron spectroscopy and Fourier transform infrared results showed the ion exchange mechanism of the M-T-LIS adsorption. From the results of the Li+ desorption experiment and recoverability experiment, DL-malic acid was used to desorb Li+ from the M-T-LIS with a desorption rate of more than 90%. During the fifth cycle, the Li+ adsorption capacity of the M-T-LIS was more than 20 mg/g (25.90 mg/g), and the recovery efficiency was higher than 80% (81.42%). According to the selectivity experiment, the M-T-LIS had good selectivity for Li+ (adsorption capacity of 25.85 mg/g in the artificial salt lake brine), which indicates its good application potential.
