An optimization study on the leaching of zinc cathode melting furnace slag in ammonium chloride by Taguchi design and synthesis of ZnO nanorods via precipitation methods

- Recovery of zinc compounds from zinc cathode melting furnace slags.
- Taguchi methodology design (L25 orthogonal array) has been used to design the experiment.
- Synthesis of ZnO nanorods by dilution and cooling precipitation methods.
- The morphology, size and structure were investigated by XRD, FESEM and BET.
- Optical properties were studied by UV-Vis spectroscopy.
