LEACHING OF ZINC AND MANGANESE FROM SPENT ZINC-CARBON BATTERIES IN ACETIC ACID SOLUTION

Bu çalışmada, asetik asit içerisinde atık çinko-karbon pillerinden Zn ve Mn'nin ekstraksiyonu çalışılmıştır. Farklı koşullar altında Zn ve Mn çözünme davranışlarını araştırmak için liç testleri yapılmıştır. Deneylerde kullanılan parametreler; karıştırma hızı, asetik asit derişimi, sıcaklık ve tane boyutudur. Çinko ve manganın çözünme verimi sırasıyla %83.59 ve %52.47 olarak bulunmuştur. 600 dev/dk karıştırma hızında, 2 M asetik asit derişiminde, -53 µm tane boyutunda, 60°C liç sıcaklığında ve 240 dakikalık liç süresinde en yüksek Zn ve Mn çözünme verimi elde edilmiştir.

Asetik Asit Çözeltisinde Atık Çinko-Karbon Pillerinden Mangan ve Çinkonun Liçi

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.
