Lithium recovery from synthetic geothermal brine using electrodialysis method

Year: 2021

Type: conference-paper

Abstract: The demand of lithium in the global market is experiencing a significant increase. The electric vehicle era is the driving force of this lithium increase phenomenon. Although the demand of lithium continues to increase every year, the available lithium resources are still not able to meet the demand, so that lithium resources with much greater potential are being considered. The main objective of this study is to extract lithium from a primary resource, geothermal brine, with a practical and environmentally friendly method. Research on the extraction of lithium resources from synthetic geothermal brine with a specific lithium composition using the electrodialysis (ED) method has been carried out. The ED device used is provided with electricity and is operated using temperature variations (30°C and 40°C) and variations in electric voltage (2 V and 4 V). The highest flux is achieved at an operating temperature of 40°C and a power supply voltage of 4 V.
