ABSTRACT: In this study, extraction of Zn and Mn from spent zinc–carbon batteries in acetic acid solution was studied. Leaching tests were carried out to evaluate the leaching behaviour of Zn and Mn under different conditions. Experimental parameters used were; stirring speed, acetic acid concentration, temperature and particle size. The zinc and manganese extraction were obtained as 83.59% and 52.47%, respectively. The maximum Zn and Mn extraction were obtained in 240 min of leaching time with the following conditions; 600 rpm stirring speed, 2.0 M acetic acid concentration, -53 µm particle size and 60°C leaching temperature.
