Indonesia is located on the path of the pacific ring of fire with 129 active volcanoes. It causes our country to have abundant geothermal resources. Geothermal potential of Indonesia is estimated at 29 GW, or 40% of the total potential in the world (Henuk and Halawa, 2016). The manifestations of geothermal are in the form of fumaroles, the land of steamy hot, sintered silica, alteration hydrothermal, and hot springs which can be found in mountainous regions (Hariyanto and Narendra Robawa, 2016). In Indonesia, geothermal energy is used to generate electricity. The process of electricity generation starts with injecting water into the bowels of the earth. The water will be heated and evaporates partially into steam pressure. Steam and water from production wells are separated using a separator. Then, steam drives the turbine and subsequently run the generator to produce electricity. While the water that is called brine is not utilized, so it’s directly returned to the bowels of the earth (Kusuma et al., 2018). Some researches showed that the geothermal brine contains several precious minerals (Si, Li, K, etc.) that should be utilized. Dieng, one of the geothermal sources in Indonesia, possesses lithium concentration of about 40-60 ppm (Pambudi et al., 2015). Based on those facts, it is proved that geothermal brine can be used as an alternative source of lithium in the future. The next question would be, what kind of technology can be applied to recover lithium from geothermal brine?
