Abstract: The disclosure relates to a method for recovering lithium (Li) and iron (Fe) from a substrate (S) containing LiFePO4/C(s), the method comprising the steps of: i.—Bringing the substrate (S) into contact with an aqueous leaching solution comprising an organic acid chosen from alkylsulfonic, alkylarylsulfonic, arylsulfonic acids, ethylenediamine-N,N?-bis(2-hydroxyphenylacetic acid) or a mixture thereof, and optionally an oxidizing agent, whereby a liquid phase L1 rich in lithium and iron is recovered; ii.—Precipitation of iron in the liquid phase L1 obtained in step i), and recovery of the iron precipitate; iii.—Precipitation of lithium in the L2 liquid phase obtained in step ii) and recovery of the lithium precipitate; and optionally iv.—Recovery of the liquid phase L3 obtained in step iii) and recovery of the organic acid used in step i).

Abstract: The support and guidance structure includes a support (14) equipped with means of guidance (16) of the mast (12) in a raising direction (Z), including a wall (32) extending in this direction (Z), and delimiting a housing (33) for the mast (12). The guidance means (16) include two guide rails (18), borne by the support (14), and two additional guidance elements (20), borne by the mast (12), each operating in tandem with a respective rail (18). Each rail (18) forms stops (18A) immobilizing the related guidance element (20) in a second direction (Y) perpendicular to the raising direction (Z) and the wall (32). The guidance means (16) include another guide rail (18), borne by the support (14), and another additional guidance element (20), borne by the mast (12), and operating in tandem with the other rail (18). The other rail (18) forms stops (18A) immobilizing the other guidance element (20) in a third direction (X) perpendicular to the raising direction (Z) and the second direction (Y).
