Secondary explosive materials, particularly nitramines, are recovered from an explosive composition containing a mixture of 2,4,6-trinitrotoluene (TNT) and at least one secondary explosive by the steps of heating the explosive composition to melt the TNT, preferably using steam, separately collecting and recovering the melted TNT, treating the thus-separated secondary explosive with a material which is a solvent for TNT and a non-solvent for the secondary explosive to dissolve the TNT, removing the non-solvent from the secondary explosive, and recovering the secondary explosive.
