Process and apparatus for separating metal from a solution in which the metal has been dissolved by use of an electrochemical cell having a cathode electrode with a metalcollecting face. A substantial centrifugal force is applied to the metal-collecting face, the centrifugal force having a substantial component in a direction perpendicular to an outward from said face, whereby metal is deposited on said face as nodules of substantially uniform shape and size. The above may be utilized in a continuous electrowinning process where the nodules are permitted to grow until they reach a size where, under the action of the centrifugal force, they break off from the metal-collecting face and are removed from the cell. The above may also be utilized in the charging of a storage battery with the nodules being maintained at a size well below the size at which they would break off. |
