Bu çalışmada, atık alkali pil tozlarındaki çinko ve manganın seçimli çözünürlüğü iki kademeli liç
yönteminin uygulanmasıyla incelenmiştir. Birinci liç kademesinde, pil tozundaki çinko sodyum
hidroksit çözeltileri kullanılarak çözündürülmüştür. Mangan içeren katı kalıntı filtrasyonla çözeltiden
ayrıldıktan sonra ikinci liç kademesinde kullanılmıştır. İkinci liç işleminde melas içeren sülfürik asit
çözeltileri liç ajanı olarak kullanılmıştır. Her bir liç basamağında çözelti derişimi, sıcaklık, karıştırma
hızı ve katı/sıvı oranının çinko ve mangan çözünmesine olan etkileri araştırılmıştır. Elde edilen bulgular
deney parametrelerinin çinko ve mangan çözünmesi üzerinde önemli bir etkiye sahip olduğunu
göstermiştir. Her iki metal için de çözünme veriminin çözücü derişimi, sıcaklık ve karıştırma hızının
artmasıyla, katı/sıvı oranının ise azalmasıyla arttığı gözlenmiştir. Sodyum hidroksit derişiminin
1.5 mol/L, reaksiyon sıcaklığının 40 °C, katı/sıvı oranının 2/500 g/mL, karıştırma hızının 500 dev/
dk ve reaksiyon süresinin 120 dk olduğu deney şartlarında atık pil tozundaki çinkonun %77’sinin
çözündüğü belirlenmiştir. Sülfürik asit derişimi, reaksiyon sıcaklığı, katı/sıvı oranı, karıştırma hızı ve
reaksiyon süresi sırasıyla 1 mol/L, 50 °C, 2/500 g/mL, 500 dev/dk ve 120 dk iken liç kalıntısındaki
manganın %85’inin çözündüğü bulunmuştur.

RECOVERY OF ZINC AND MANGANESE FROM WASTE ALKALINE BATTERY POWDER BY TWO-STAGE LEACHING PROCESS

Öz

In 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.
