Abstract
A process for the recovery of TNT and aluminum from tritonal-containing military shells. The process uses a solvent in which the TNT is substantially soluble, but not the aluminum. This results in a liquid organic solvent phase and a solid aluminum particle phase. The aluminum particles are recovered by conventional solid-liquid separation techniques, such as filtering, gravity settling, and the like. The TNT is recovered from the solvent by flashing or evaporating the solvent and recrystallizing the TNT.
