A cell assembly (10) is described for extracting mineral from a flowing electrolyte, including a housing having an inlet (23) and an outlet (22) for passing electrolyte through the housing. The housing confines the flow of electrolyte through a removable sleeve-like cathode (13) and is also provided with an anode (21) extending into the housing, and electrical connecting means for connecting an electrical circuit to the cathode (13) and the anode (21). The housing is preferably a fixed cylindrical housing and includes a removable top cap supporting an anode assembly for removal therewith. The anode (21) is supported concentrically and is part of an anode assembly which extends fully through the housing to be located concentrically in the housing with a bottom support (31) in the housing by locating means provided on the distal end of the anode (21). It is also proferred that the anode (21) includes an exposed conductive portion (29) within end extremities of the sleeve-like cathode.
Cette invention concerne un ensemble de cellules (10) destiné à l'extraction de minerai d'un électrolyte fluide. Cet ensemble comporte un habitacle ayant un orifice d'entrée (23) et un orifice de sortie (22) permettant de faire traverser ledit habitacle par un électrolyte. Cet habitacle confine le flux d'électrolyte à travers une cathode (13) amovible de type manchon et il est pourvu d'une anode (21), disposée en son sein, et d'un organe de connexion électrique permettant de relier la cathode (13) et l'anode (21) à un circuit électrique. Cet habitacle est de préférence fixe et cylindrique et il comporte un capuchon supérieur amovible supportant un ensemble anode avec lequel on peut le retirer. L'anode (21) est soutenue concentriquement et fait partie d'un ensemble anode qui traverse entièrement l'habitacle et que l'on doit placer concentriquement avec un support inférieur (31) dans l'habitacle en positionnant un organe équipant l'extrémité distale de cette anode (21). De préférence, l'anode (21) comporte une partie conductrice (29) exposée entre les extrémités terminales de la cathode de type manchon.
