摘要： The invention discloses a method of controlling the size distribution of electroconductive particles constituting a particulate electrode in an electrochemical cell. Particles are extracted from the particulate electrode and are subjected to elutriation, the flow of elutriating fluid being such that particles larger than a predetermined size settle against the flow of fluid, while the other particles are carried along by the elutriating fluid and are eventually returned to the electrochemical cell.

摘要： There is disclosed an electrochemical process and cell, the electrochemical cell comprising an anode compartment through which flows an anolyte and a cathode compartment through which flows a catholyte separated, at least in part, by an ion-permeable wall, wherein the operating pressures within the anode compartment and the cathode compartment are controlled in a manner such that there is not a large difference of pressure across said ion-permeable wall. The operating pressures are advantageously controlled by a flow impeder constituted by a plurality of perforated plates or baffles disposed within an electrode compartment of the cell.

摘要： An electrolytic cell and process are described for use in a plant for the cathodic recovery of a metal from, for example, an ore. The cell includes one or more intermediate compartments which are bounded by ion-permeable separators and are disposed between the anode compartment and the cathode compartment. In the process, an aqueous solution of a salt of the metal is circulated around a first circuit including the cathode compartment of the cell, and an acid solution is circulated around a second circuit including the anode compartment. The fluid in the intermediate compartment(s) may also be circulated.
