Abstract (en)
[origin: WO2021255377A1] The present invention relates to a method for recovering ammonium perchlorate from a solid composite propellant, said method being carried out at a temperature of less than 50°C involving maceration of solid composite propellant fragments in the form of an aqueous suspension, said method being terminated when the ionic conductivity in the aqueous suspension reaches a stabilized value, less than 60 mS/cm.
