Abstract
Apparatus and methods for the recovery of metal values from an electrolyte in an electrodeposition or electrowinning cell are disclosed. A bottom baffle assembly supporting a plurality of bubble tubes and alignment devices is urged upward from the bottom of the electrolytic cell. An electrode assembly, having alignment means which cooperate with the alignment devices on the bottom baffle assembly, engages and aligns with the bottom baffle assembly when the electrode assembly is lowered into the electrolyte. Thereby, the bubble tubes are aligned to provide sheets of bubbles between the anode and cathode faces. The invention also features methods and apparatus for separating the electrodes, after the electrodeposition or electrowinning process, by pulling them apart in the horizontal direction to minimize the chance of damage to the electrodes.
