Before both chemical treatments, lepidolite was calcined at 800ºC and was transformed in a more reactive species, β-spodumene. The H 2 SO 4 digestion at 175ºC (followed by water leaching) allowed 88% Li recovery into the solution in 30 min. By the contrary, the HCl leaching process carried out at 90ºC also achieved similar yields but
