“…Mineral carbonation mainly applies Ca and Mg to react with CO 2 to form CaCO 3 and MgCO 3 . [86][87] In terms of the great content of Ca and Mg in brine, mineral carbonation using brine may further facilitate CO 2 uptake. This direction of research has received recent attention, and there is also a review that evaluates the development possibilities in detail.…”

“…Sr is naturally present in seawater, and variation in the 87 Sr/ 86 Sr ratio in seawater over time provides a basis for studying the stratigraphy and geochronology of marine biogenic carbonates and phosphates. Because 87 Sr is radioactive and originates from the 𝛽-decay of 87 Rb, recovery of Sr mostly focuses on 88 Sr (82.6% in Sr isotope). On the other hand, Cu in brine is mainly from the desalination procedures.…”

Desalination brine is a concentrated stream that is generated during the desalination process. Brine commonly has high salinity and TDS (total dissolved ions), which contains ions such as Na+, K+, Ca2+, Mg2+, Cl−, SO42−, HCO3−, PO43−, and some critical elements. Currently, the brine treatment mainly applies direct disposal, like surface water discharge, sewer discharge, deep‐well injection, and evaporation ponds. However, these methods can cause harm to marine ecosystems, soil, and groundwater. Therefore, brine can be regarded as a resource to be reutilized. This work then aims to highlight the novel developments of brine application. For example, Na, Ca, and Mg in brine can be employed for carbon capture and utilization with ammonia, amines, and alkaline substances. With slight adjustment, brine can also be directly used as irrigation water, aquaculture water, and the activation of biochar. Furthermore, brine holds a higher concentration of critical elements, which makes many countries and scholars start to conduct element extraction, reducing the amount of ore exploitation. At last, the major obstacles related to these advancements in sustainability, expenses, and technological aspects are outlined, and promising research trends of brine reutilization are also suggested.
