ABSTRACT:
In processes for electrochemically extracting the metals contained in spent electrical accumulators, the accumulators are first immersed in activation tanks and then placed in dissolving tanks after connecting their poles to the direct current supply cables.
This patent application discloses a plastics frame structure comprising numerous seats, each of which can house one accumulator. Each frame is provided with current-carrying bars from which there branch plastics-covered copper or aluminum cables, on the ends of which there are special contacts which are mounted on to the accumulator poles. The contacts are constructed in such a manner so as to protect the accumulator poles from being corroded by the electrolyte solution into which the frame is immersed.
The use of the frame according to the invention simplifies and accelerates all the process operations, leading to a large reduction in operating costs.
