Mining valuable minerals from seawater: a critical review
IntroductionPotentially Profitable Minerals from Seawater and Seawater BrineMethods of MiningAdsorption/Desorption ProcessEconomic AnalysisConclusionsAcknowledgementsMinerals have been mined from seawater since ancient times. It has been recorded that common salt (NaCl) was extracted even before 2000 BC in China and also in the Old Testament period.1,3 Currently the four most concentrated metals Na, Mg, Ca and K are commercially extracted in the form of Cl−, SO42−, and CO32−.2 Mg is also extracted as MgO.1,7Mineral elements with low concentrations have not been recovered from seawater because their market values are much l
Wetting, Scaling, and Fouling in Membrane Distillation
Membrane distillation (MD) has been garnering increasing attention in research and development, since it has been proposed as a promising technology for desalinating hypersaline brine from various industries using low-grade thermal energy. However, depending on the application context, MD faces several important technical challenges that would lead to compromised
