Definitions

  • the invention relates to a method for operating copper electrolysis cells, which comprise a plurality of vertically and mutually parallel anode and cathode plates, a longitudinal electrolyte inlet and an electrolyte effluent, and a novel copper electrolysis cell.
  • m is the mass of copper produced in g
  • M the molar mass of copper in g / mol
  • i the current density in A / m 2
  • A the electrode surface in m 2
  • t the time in s
  • z the valence of the reaction ions involved
  • F the Faraday constant in As / mol.
  • the currently technically feasible current densities are, for example, in a copper refining electrolysis at a maximum of 350 A / m 2 . This value results from the fact that in a technical electrolysis cell only about 30-40% of the theoretical limiting current density can be driven.
  • This theoretical limiting current density i limit (equation 2) is a function of the copper ion concentration in the electrolyte (c °) and the diffusion layer thickness ⁇ N at the electrode. N, the number of ions involved in the process, F, the Faraday constant and D, the diffusion coefficient, are constant.
  • i border n ⁇ F ⁇ D ⁇ c 0 ⁇ N
  • the types of refining electrolysis cells used today are distinguished by the fact that the electrolyte is fed in on the front side and removed again on the opposite end side.
  • the main flow therefore takes place between the cell wall and the electrodes or the cell bottom and the lower edges of the electrodes.
  • This externally applied flow also called forced convection
  • the flow between the electrodes is determined by the natural convection that results from the density difference of the electrolyte in front of the cathodes (lighter electrolyte due to depletion of copper ions) and before the anodes (heavier electrolyte due to the accumulation of copper ions).
  • containers for electrolytic metal extraction are known in which, to achieve a parallel flow, the electrolyte inlet and outlet into or out of the electrode space is effected by perforated plates arranged parallel to the longitudinal walls.
  • a parallel partition with openings for the passage of electrolyte into the electrode space is arranged only on one longitudinal wall.
  • the passage openings are distributed over the entire electrode height and are aligned with the electrode interstices.
  • a relatively simple means of achieving parallel flow in conventional electrolysis cells is the provision of tubular electrolyte supply and drainage devices which direct the electrolyte in opposite directions between the bath longitudinal walls and the electrode side edges in the two free spaces. Due to the larger cathode width, a jam of the electrolyte occurs in front of the cathode side edges, as a result of which the latter partially flows into the respective electrode gap.
  • electrolytic bath in which the parallel flow is achieved by an inlet of the electrolyte from the bath floor.
  • an electrolysis cell is described with longitudinal electrolyte inlet, in which on one or both longitudinal sides extending over the entire length of the bath extending to just below the cathode lower edge, down and closed at the sides, above the electrolyte level open electrolyte inlet box is attached to the the electrodes facing horizontal and parallel to the electrodes aligned through openings, which in the region of the lower cathode edges over a extend certain area of the cathode spaces.
  • the cross-sectional area of all the passage openings is smaller than the open horizontal cross-sectional area at the top of the electrolyte inlet box in order to achieve a slight overpressure.
  • the channel cell requires a large pump capacity to achieve the high flow rates.
  • To separate the entrained anode sludge continuous electrolyte filtration is required.
  • Leiteinbauten as a flow straightener and the arrangement of appropriately shaped partitions is associated with a very large material and manufacturing effort.
  • the hanging of these baths with the electrodes requires great care, since the desired electrolyte circulation is guaranteed only if the required geometric conditions are precisely met.

Likewise, extensive changes to and complex installations in the cell should be avoided.
  • This object is achieved in a first aspect in a method of the type mentioned above in that the electrolyte via the electrolyte inlet horizontally and parallel to the electrodes in each electrode gap at the level of the lower third of the electrodes at a speed of 0.3 to 1, 0 m / s is flowed, wherein the cathode plates are arranged stationary relative to the inflow direction.
  • the electrolyte is flowed into the cell at a rate of 0.3 to 0.6 m / s.
  • a further improvement of the method is possible if the electrolyte is not applied as usual and applied in the examples on the front side of the cell but longitudinally drained.
  • the method according to the invention has the additional advantage that it can be carried out even with existing electrolysis cells without great effort with few changes to the existing facilities.

Abstract

La présente invention concerne un procédé pour faire fonctionner des piles électrolytiques au cuivre comprenant une pluralité de plaques d'anode et de cathode disposées perpendiculairement et parallèlement entre elles, un élément d'amenée d'électrolyte disposé longitudinalement et un élément d'évacuation d'électrolyte. Selon l'invention, on fait circuler l'électrolyte par l'élément d'amenée d'électrolyte horizontalement et parallèlement aux électrodes dans chaque espace intermédiaire entre électrodes respectivement à la hauteur du tiers inférieur des électrodes à une vitesse de 0,3 à 1,0 m/s, les plaques de cathode étant disposées en un emplacement fixe vis-à-vis de la direction de circulation. On obtient ainsi un guidage optimisé du flux de l'électrolyte vis-à-vis des électrodes, ce qui conduit à une augmentation de la densité de courant limite.
