Hydrometallurgical Synthesis of pure zincite (ZnO) powder from dead zinc carbon batteries for use in the manufacturing of antimicrobial products

Year: 2025

Type: article

Abstract: The conversion of waste materials in our environment into useable chemical products is a popular issue these days. Here, we report on the production of zincite powder using a very simple hydrometallurgical method. Within two hours, 92.23% of the original 10 g/L SZCB reacted at ideal leaching conditions (2.5 mol/L HCl, 80°C). The result predicted the diffusion model as rate determining step, with calculated Ea of 28.53 kJ/mol. The precipitated hydroxide was calcined to produce pure zincite powder of yield 85.2%. Analyses using X-ray diffraction (XRD) and scanning electron microscopy (SEM) revealed that the high purity ZnO existed as a flower-like spherical aggregation and antimicrobial testing was later carried out to be reported in part B of the research.
