Abstract : A process is provided for reclaiming materials from photoflash cartridges which are comprised of aluminum, barium nitrate and potassium perchlorate. The photoflash composition is dumped into heated water to dissolve barium nitrate and potassium perchlorate and the solution is then filtered to remove aluminum. Then the solution is cooled to precipitate the barium nitrate and the potassium perchlorate and the precipitated salts are then removed by filtering.
