![]() ![]() Core samples from the Danakil Depression potash exploration reported up to 20-40 ppm in the carnallite and bischofite layers of the evaporite sequence. However, brines produced during precipitation of trona and halite contain about 0.009 ppm lithium, which is well below economically extractable concentrations. Lithium enrichment was also noted in residual brines from multi-stage solar evaporation pans during soda-ash production. Hot springs in the Dallol contain up to 20 ppm lithium. ![]() Lithium concentrations are elevated in brine lakes, brine ponds, and hot springs of the Danakil Depression. Lithium contents in water samples from rift-bound lakes like Abijata, Shala, Chamo, Abaya, and Chew Bahir show low concentrations consistent with background values for surface waters. The current research focused on known brine lakes and hot springs in the Danakil Depression and the Main Ethiopian Rift. Ethiopia has potential for lithium resources related to pegmatites and to rift-bound brine deposits. A B S T R A T Lithium is a metal with increasing demand on the global market mainly for its application in lithium ion batteries for electric vehicles. ![]()
