ABSTRACT:
Aluminum is recovered from solid rocket propellant containing a small amount of oxidizer by depolymerizing and dissolving propellant binder containing functional or hydrolyzable groups in a solution of sodium methoxide in an alcohol solvent optionally containing an aliphatic or aromatic hydrocarbon co-solvent and then filtering the solution to recover substantially all the aluminum in active form.
