摘要： A METAL IS RECOVERED FROM A SOLUTION IN WHICH THE METAL IS PRESENT IN IONIC FORM BY SUPPORTING A THIN MOVING LAYER OF THE SOLUTION IN CONTACT WITH AN ELECTRODE, IMPRESSING AN ELECTRIC POTENTIAL ACROSS THE MOVING LAYER, AND MIXING THE SOLUTION WITHIN THE LAYER AS IT TRAVELS PAST THE ELECTRODE SO AS TO REPLENISH METAL IONS AS THEY ARE DEPLETED FROM IMMEDIATELY ADJACENT THE ELECTRODE SURFACE AT WHICH PLATING OF THE METAL OCCURS. APPARATUS FOR CARRYING OUT THIS METHOD INCLUDES ELECTRODE MEANS AND A MOVING BELT WHICH SUPPORTS THE THIN LAYER OF SOLUTION IN CONTACT WITH THE ELECTRODE MEANS, THE MOVEMENT OF THE BELT ACTING TO ENSURE FLOW OF THE SOLUTION PAST THE ELECTRODE AND TO SIMULTANEOUSLY AGITATE THE MOVING LAYER TO EFFECT MIXING OF THE SOLUTION WITHIN THE LAYER. THE METHOD AND APPARATUS ARE OF PARTICULAR UTILITY IN THE RECOVERY OF SILVER FROM VISCOUS FIXING SOLUTIONS EMPLOYED IN PHOTOGRAPHIC PROCESSING.

摘要： A non-agitated electrolytic cell for the recovery of silver from photographic chemical solutions which comprises a vertical tubular cathode enclosing an anode. The cell is operated at a low current density of between 50 and 100 milliamps per square foot of effective cathode area and the solution rich in silver is supplied continuously or in batches to the lower end of the cell, while the solution depleted of its silver content flows simultaneously from the top of the cell. For processing larger volumes of solution a cellular cathode assembly is used defining a bank of such cathode cells, there being a corresponding anode assembly with an anode disposed in each cell. The anodes are connected in isolated groups, each group being placed in circuit with an overload protection device, so that occurrence of a short-circuit in one group of anodes does not affect the operation of the remaining groups.

摘要： A system for recovering minerals, mineral ores and their compounds from the bottom of the sea and other deep water areas which employs a sled-like unit having a reaction chamber with an open bottom adapted to be dragged along the ocean floor while the reaction chamber is supplied with solvents and/or reagents which will react with the minerals and/or ores and other mineral bearing materials desired to be recovered and means associated with the reaction chamber for collecting the desired materials in more concentrated form and for bringing them to the surface which includes subjecting mixtures of the desired materials and waste to electrical deposition and/or chemical segregation. In one form of the apparatus employed the desired materials on the ocean floor are treated with chemical solvents and reagents which will react with the minerals and/or the compounds sought and mixtures of the solution and reaction products with some waste forming material are brought to the surface for extraction of the desired products by electrolytic deposition and segregation in a surface unit.

摘要： The recover of silver from waste silver solutions, especially spent photographic processing liquids, is effected with a silver recovery machine, such as a rotating cathode machine, and an auxiliary tank installed immediately upstream of the silver recovery machine to receive the silver waste solution from film processing equipment or other source. A metering pump delivers the waste solution from the auxiliary tank to the silver recovery machine, the pump being started and stopped in dependence upon changes in the level of the waste solution in the auxiliary tank. The silver recovery machine is arranged to operate only while the metering pump is running, this operation being at a constant current setting.

摘要： An efficient electrolytic recovery cell which has an anode, a cathode surrounding the anode, and a pump adjacent the cathode for directing a flow of electrolyte into the space between the anode and the cathode. The pump directs the flow of electrolyte in a generally horizontal direction to cause electrolyte to helically descend between the anode and the cathode. The pump has a hollow tube connected to it and running adjacent the cathode to recirculate the electrolyte coming from the bottom of the cathode.
