Abstract
L'invention concerne une cellule électrolytique pour l'extraction de métal (70) à partir d'un composé correspondant dissous dans un électrolyte fondu, qui comprend: un bac de cellule à isolation thermique (10,20) et un couvercle de cellule à isolation thermique (30) permettant de recueillir un électrolyte (40) et de le maintenir dans un état fondu sensiblement sans croûte; et un dispositif d'alimentation (50) de particules (60) du composé métallique vers l'électrolyte fondu (40). Le dispositif d'alimentation (50) comporte un tube d'alimentation (51) qui s'étend dans le bac (10,20), avec une extrémité tubulaire (52) située entre l'électrolyte fondu (40) et le couvercle (30) et qui a une direction axiale sensiblement horizontale. Ce dispositif (50) fournit les particules (60) au tube d'alimentation (51), le long de ce tube (51) et via une ouverture (53) dans l'extrémité tubulaire (52), aux fins de distribution sur l'électrolyte (40). L'ouverture (53) se trouve à un bout de l'extrémité tubulaire (52) et permet de distribuer les particules (60) depuis le tube (51) sensiblement le long de la direction axiale de l'extrémité tubulaire (52). L'ouverture (53) peut être coaxiale avec l'extrémité tubulaire (52) ou bien hors-axe.
