  • RECOVERY OF TANTALUM FROM CAPACITOR WITH

    tantalum was successfully able to recover from the capacitors by this technique. If sub-critical BZA is found to be applicable to chemical recycling the present chemical recycling processes using NMP solvents will be alternate to more environmentally benign ones. 2. Materials and Methods Tantalum capacitors were used as starting materials.
