Abstract

A cell for the electrowinning of a metal from a compound of the metal dissolved in a molten electrolyte (1), comprises a cell trough containing the molten electrolyte (1) in which the metal compound is dissolved and a cell cover (5) located above the molten electrolyte (1). The cell further comprises an anode (10) that has an anode body (30) and an elongated anode stem (20) having a bottom end (21) connected to the anode body (30). The anode stem (20) extends through a stem passage (6) in the cell cover (5) and suspends the anode body (30) in the molten electrolyte (1). The anode body has a bottom surface (31) which is immersed in the molten electrolyte (1) and which is active for the electrolysis of the metal compound. A delivery duct (22) for supplying particles of the metal compound (3) to the electrolyte (1) extends along the anode stem (20) through the stem passage (6) . The delivery duct (22) is arranged to deliver the metal compound particles (3) to the electrolyte (1) at an exit point (26) of the duct (22) located between the cell cover (5) and the anode body (30). The cell cover (5) may comprise: one or more preformed components, usually one or more insulating plates, placed above the electrolyte; and/or an electrolyte crust formed in-situ above the electrolyte by freezing its surface.
