“…Precipitates were formed by mixing carbonate-bearing and Li-bearing solutions 20 with and without inorganic ions observed in the mineral type locality brine from Lake Zabuye. 21 Interactions between different ions in solution were examined in situ using Raman spectroscopy and compared with predictions from thermodynamic solution speciation calculations. In contrast, direct interaction between different ions in solution and the solid zabuyelite phase were examined in situ using attenuated total reflectance infrared spectroscopy.…”

Lithium-bearing brines are an increasingly attractive source of Li for extraction. One extraction mechanism is the removal of Li from the fluid phase through the precipitation of zabuyelite (Li2CO3). The chemistry of the brine plays an important role in this process because ions in solution can compete for the components of the Li-carbonate phase. Here we explore the effect of different brine components on the precipitation of zabuyelite using experiments and computational simulations. Crystals formed in all solutions showed morphological evidence for potential transformation from a precursor phase. Our study indicates that Ca2+ and SO42– are incorporated into the precipitated zabuyelite crystals. Sulfate also interacts directly with specific surfaces on the growing crystal and is expected to form ion pairs with Li+ in solution. Similarly, Na+ appears to form ion pairs in solution with the carbonate ion, slowing nucleation of zabuyelite in the experiments. K+ and Cl– may interact with the growing zabuyelite crystals but do not appear to affect zabuyelite nucleation and growth times. These experiments highlight the importance of understanding the solution chemistry on zabuyelite formation in order to predict the efficiency of extraction processes and the purity of the solids.

“…Evaporation experiments are very effective for studying this development. Usiglio (1849) first proposed a salt precipitation sequence for seawater from the Mediterranean on the basis of evaporation experiments; Valyashko (1965) proposed a salt precipitation sequence for seawater from the Black Sea; Chen (1983) divided the salt precipitation sequence of water from the Yellow Sea into ten stages, that are similar to the Usiglio (1849) sequence. Sequences have also been proposed for brine from inland basins in China (Wang, 1982;Wang et al, 1992b).…”

Lop Nur is located in the eastmost end of the Tarim Basin in Xinjiang, Northwestern China. This study covers the hydrochemical characteristics and evolution of underground brine in Lop Nur based on analytical data of 429 water samples (mainly brine). It is found that in the NE‐SW direction, from the periphery to the Luobei sub‐depression, while the hydrochemical type varies from the sodium sulfate subtype (S) to the magnesium sulfate subtype (M), the corresponding brine in the phase diagram transfers from the thenardite phase (Then) area, through the bloedite phase (Blo), epsomite phase (Eps), picromerite phase (Picro), and finally to the sylvite phase (Syl) area. As for the evolution degree, the sequence is the periphery < Luobei horizontally and the overlying glauberite brine < the underlying clastic brine vertically. It is concluded that the oxygen and hydrogen isotopic compositions of the brine have been evidently affected by evaporation and altitude effect, as well as the changes in local water circulation in recent years. Boron and chloride isotopic compositions show that the glauberite brine is formed under more arid conditions than the clastic one. The strontium isotopic composition indicates that the Lop Nur brine mainly originates from surface water; however, deep recharge may also be involved in the evolution of brine according to previous noble gas study. It is confirmed that the brine in Lop Nur has become enriched with potassium before halite precipitates over the full course of the salt lake evolution. Based on chemical compositions of brine from Drillhole LDK01 and former lithological studies, the evolution of the salt lake is divided into three stages and it is inferred that the brine in Lop Nur may have undergone at least two significant concentration‐dilution periods.

The 273.15-K-Isothermal Evaporation Experiment of Lithium Brine from the Zhabei Salt Lake, Tibet, and its Geochemical Significance

The Zhabei Salt Lake is located in the hinterland of the northern Qinghai-Tibet Plateau, China. The salt lake is of the sodium sulfate subtype and rich in lithium. In order to exploit lithium in the brine of the salt lake, a 273.15 K-isothermal evaporation experiment of the brine from the Zhabei Salt Lake was carried out for the first time. Based on the 273.15 K-isothermal phase diagram of the quaternary system Na ? , Mg 2? //Cl -, SO 4 2--H 2 O, the evaporation-crystallization path of the brine was drawn and the sequence of salt precipitation was confirmed. The experimental results show that due to the large amount of SO 4 2-precipitated as mirabilite, the concentration of SO 4 2-in the brine was stabilized at about 0.25 mol L -1 , thus avoiding formation of Li 2 SO 4 Á3Na 2 SO 4 Á12H 2 O in the early stages of the low-temperature evaporation process. Lithium was effectively concentrated to 1.09 mol L -1 in residual mother liquor as the evaporation rate reached 96.76 %, and the molar ratio of Mg/Li decreased from 1.25 to 0.23. The enrichment behavior of lithium is described as a power function of Y = k(1 -X) -1 , where Y = the concentration of lithium in the residual brine, X = the extent of evaporation, and k = the initial value of lithium concentration of the brine. In addition, the experiment suggests that the salts precipitated from the brine of the Zhabai Salt Lake contain not only the mineral assemblage with the characteristics of carbonate-type salt lakes, such as borax and lansfordite, but also the mineral assemblage with the characteristics of sulfate-type salt lakes, such as carnallite and lithium sulfate monohydrate. This finding, the data from the Zhabei Salt Lake's brine in 1978, and the distribution characteristics of the hydrochemical zones of salt lakes on the Qinghai-Tibet Plateau, indicate that this salt lake is in a special stage of transition from a sulfate-type salt lake to a carbonate-type.
