A method for preparing a crystallized solid material of formula LiCl.2Al(OH)3,nH2O with n being comprised between 0.01 and 10, includes mixing in an aqueous medium, at least one source of alumina and at least one source of lithium in order to obtain a suspension, filtering the resulting suspension obtained for obtaining a slurry, followed by drying the obtained slurry at a temperature between 20 and 80° C. for a period between 1 h and 12 h, then shaping by extrusion the resulting dried slurry, directly after the drying to obtain extrudates, where the shaping was carried out without any binder, and then the drying of the obtained extrudates at a temperature comprised between 20 and 200° C. for a period between 1 hour and 20 hours, in order to obtain the crystallized solid material of formula LiCl.2Al(OH)3,nH2O as extrudates. A method for extracting lithium from saline solutions uses the thereby prepared material. |
