dc.description.abstractIn this work, the selective dissolution of zinc and manganese in the waste alkaline battery powders was investigated by applying two-stage leaching method. In the first-stage of leaching, zinc in the battery powder was dissolved using NaOH solutions. The solid residue containing manganese was separated from the solution by filtration and used in the second leaching step. Sulfuric acid solutions containing molasses was used as leaching agent in the second-stage leaching treatment. In each leaching step, the effects of solution concentration, temperature, stirring speed and solid to liquid ratio on the dissolution of zinc and manganese were examined. The findings obtained showed that the experimental parameters had a significant effect on the dissolution of zinc and manganese. It was observed that the dissolution efficiency for both metal increased with an increase in the solution concentration, temperature and stirring speed, and with a decrease in the solid to liquid ratio. At the experimental conditions of a sodium hydroxide concentration of 1.5 mol/L, a reaction temperature of 40°C, a solid to liquid ratio of 2/500 g/mL, a stirring speed of 500 rpm, and a reaction time of 120 min., it was determined that 77% of zinc in waste battery powder was dissolved. While concentration of sulfuric acid, temperature, solid to liquid ratio, stirring speed, and reaction time were 1.5 mol/L, 50°C, 2/500 g/mL, 500 rpm, and 120 min. respectively, it was found that 85% of manganese in the leach residue was dissolved. © 2019 Union of Chambers of Engineers and Architects of Turkey.
