Abstract

Bu çalışmada sülfürik
asit kullanılarak liç ile çinko oksit cevherinin kazanımı araştırılmıştır. Liç
süresi, asit konsantrasyonu, liç sıcaklığı, partikül boyutu ve katı/sıvı oranı
gibi bazı parametrelerin etkileri maksimum çinko ekstraksiyonu ve minimum asit tüketimi
için araştırılmıştır. Optimum liç koşulları 120 dakika liç süresi, 55 g/L H2SO4
asit konsantrasyonu, 25 ˚C liç sıcaklığı, -780 µm partikül boyutu ve 1/10
katı/sıvı oranı olarak belirlenmiştir. Bu optimum koşullarda, %93.42 çinko
ekstraksiyonu ve 1.58 (ton H2SO4/ çözünen ton Zn) asit
tüketimi elde edilmiştir.

Abstract



This study investigates the extraction from zinc
oxide ore by leaching using sulfuric acid. Effects of some parameters such as
leaching time, acid concentration, leaching temperature, particle size and
solid/liquid ratio were studied for maximum zinc extraction and minimum acid
consumption. Optimum leaching conditions were determined to be 120 minutes of
leaching time, 55 g/L H2SO4 of acid concentration, 25 ˚C
of leaching temperature, -780 µm of particle size and a solid/liquid ratio of
1/10. In these optimum conditions, 93.42% of zinc extraction and 1.58 (ton H2SO4/dissolved
ton Zn) of acid consumption were achieved.
