Lithium extraction from brine water Tirtasanita Bogor, Indonesia by evaporation method

Abstract

The objectives of this research are to characterize the chemical composition of brine water, Tirtasanita Bogor, Indonesia and investigate the influence of brine water vaporization ratio on lithium content and other chemical elements of brine water. The research method is brine water evaporated at boiling point using distillation equipment with various evaporation ratios up to 50 percent; 75 percent; 80 percent; 87.5 percent and 90 percent volume of brine water. The distillation process produces distillate and brine water liquid containing salt deposits. The brine water liquid from the evaporation process was then filtered to separate the filtrate of brine water and salt deposit. Distillate and filtrate of brine water were analysed by ICP-OES to know the chemical composition of both such as Li, K, Na, Ca, and Mg. The salt deposits were characterized by SEM-EDS. The experimental results show that the chemical compositions of brine water Tirtasanita Bogor, Indonesia are 17.27 ppm Li; 409.98 ppm K; 1929.87 ppm Na; 185.71 ppm Ca; 146.02 ppm Mg. From the result of SEM-EDS analysis shows that salt deposit has a spherical morphology with the dominant Ca content. This salt deposit is indicated as CaCO3 compound.
