Abstract Scope The increasing demands for metals with gradual depletion of un-renewable resources warrant the need for industrial metals recovery from secondary sources including zinc-carbon batteries. The recycling from wastes is important as cost of safe disposal of its hazardous components is quite high compared to the amount of waste produced-cum-limited storage capacity. For instance, sub-Sahara African countries’ including Nigeria has been found to have dominance of non-rechargeable spent batteries containing precious metals content. These metals which may be toxic are valuable industrial elements if re-processed. In this work, combinations of acid leaching, solvent extraction and precipitation techniques were utilized in processing spent Tiger Head Zinc-carbon batteries assaying majorly 41.30wt% ZnO, 4.30 wt%Fe2O3 and 2.69wr% MnO2. At optimal conditions, the leach liquor was selectively treated to achieve 96.7% zinc recovery efficiency by Cyanex®272 extractant prior to its beneficiation as zinc oxide suitable as coating and industrial raw materials for some defined industries.
