摘要： The present invention relates to a device and method for electrolytic deposition of metals on conducting particles. The conducting particles are completely immersed in a liquid and allowed to flow across a particle contacting surface of a cathode support. The particles flow across the surface and into a reservoir. Electrical contact is made between the negative pole of a DC power supply and the conducting particles. An anode mesh is placed above and parallel to the top face of the particle bed such that the mesh does not touch the particle bed but remains a controlled distance from it. The anode mesh is connected to the positive terminal of the DC power supply. A significant aspect of the present invention is that the device does not require a separator between the particle bed and the anode.

摘要： Disclosed herein is a process for dissolving and recovering noble metals form used catalysts. Noble metal components are leached out from particles supporting or containing at least one noble metal or noble metal compound by subjecting particles them to electrolysis, with the electrolyte being an acid, in the anode compartment of an electrolytic cell which divided by a diaphragm into anode and cathode compartments, and the resulting solution containing noble metals is subjected to electrolysis in a fluidized bed electrolytic cell, thereby causing the noble metals to separate out on to the fluidizing cathode particles. The thus deposited noble metals are again leached out in an electrolytic cell.

摘要： A process and an apparatus for electrowinning metal from metal bearing solutions is disclosed. A support solution containing a predetermined metal concentration is continuously recirculated through a cell having a porous grid supporting a bed of particulate conducting particles at a sufficiently high flow rate so as to fluidize and expand the bed by 5 to 25%. A gas is continuously fed through the bed of conducting particles so as to strongly agitate the particles at low bed expansion to maintain good mixing and uniform fluidization of the bed of particles. The cell includes an electrode arrangement suspended from the top of the cell and immersed into the bed of fluidized conducting particles. Such electrode arrangement consists of at least one cathode feeder electrode in physical contact with the fluidized particles to make the particles cathodic and so cause the metal ions to deposit on the particles, and at least one anode electrode separated from the cathodic particles by a membrane which allows the free passage of ions while preventing physical contact with the particles. To make the process continuous or semi-continuous, the cell has an inlet for adding small seed particles and an outlet adjacent to the bottom for withdrawing large product particles.

摘要： A process for the electrodeposition of metal onto the particles of a fluidised bed cathode is of particular use in the electro-winning of metals. Agglomeration of particles is substantially avoided by the elimination of sharp corners within the portion of the cell where there is electrodeposition and by the removal of particles from the fluidised bed cathode before they reach a size where they tend to lodge adjacent structural surfaces within the cathode compartment. Flow of electrolyte into the base of the cathode compartment may conveniently be distributed by a porous plate or a "V" shaped trough.
