• The recovery of lithium from geothermal water at Hatchobaru in Kyushu, Japan, was investigated. A coprecipitation method using aluminium salts was employed. The lithium concentration in the geothermal water used in the present study was about 10 ppm. To make our experimental results more applicable for geothermal water, a reference lithium solution (10 ppm) was also studied as a control solution. A perfect recovery of lithium was obtained for the reference lithium solution by choosing appropriate conditions. For geothermal water, the yield of Li was not so good as in the control solution. However, an almost complete recovery of lithium was attained for geothermal water by the removal of calcium ions and polymerized silica. The mechanism of Li recovery was also considered.
