Abstract (en)

[origin: WO2015162272A1] The invention relates to a process for preparing a crystalline solid material of formula LiCl.2Al(OH)3.nH2O with n being between 0.01 and 10, said process comprising at least the following steps: a) a step of mixing, in an aqueous medium, at least one source of alumina and at least one source of lithium in order to obtain a suspension, b) a step of filtering the suspension obtained in step a) in order to obtain a paste, c) a step of drying the paste obtained at the end of step b), d) a step of shaping said dried paste, directly after the drying step c) in order to obtain a shaped solid material, said shaping step d) being carried out in the absence of binder, and e) the drying of the shaped solid material obtained, f) a step of hydrothermal treatment in order to obtain the shaped crystalline solid material of formula LiCl.2Al(OH)3.nH2O. The invention also relates to a solid material obtained according to this process and to a process for extracting lithium from saline solutions using the material thus prepared.
