Abstract
In a method for electrochemical ammunition disposal and material recovery, ammunition cartridges are placed in an acidic aqueous solution that is in contact with a cathode and an anode. The ammunition cartridges have a casing that includes an alloy of copper and zinc. The ammunition cartridges are agitated in the acidic aqueous solution as a voltage is applied between the anode and the cathode. The applied voltage is effective to oxidize and dissolve zinc from the copper-zinc alloy. Copper metal derived from the alloy can be recovered as a solid, and zinc ion derived from the alloy can be recovered as a solution.
