Niğde (Ulukışla) kompleks Pb-Zn cevherinin optimum flotasyon şartlarının belirlenmesi

Öz

Bu çalışmada, Niğde-Ulukışla yöresine ait Pb-Zn kompleks cevherinin optimum flotasyon şartları araştırılmıştır. Deneysel çalışmalarda kullanılacak olan cevher numunesinin serbestleşme tane boyutu (d80) belirlenmiş ve mineralojik analizleri gerçekleştirilmiştir. Flotasyon deneyleri, %30 katı oranında, 10 L/dk. hava akım hızında, 1250 dev/dk. karıştırma hızında ve pH=9’da gerçekleştirilmiştir. Öğütme, Pb ve Zn kaba flotasyonu devresinde kullanılması gerekli olan reaktifler ve miktarları belirlenmiştir. Deneylerde, öğütme devresinde 8 dakika, Pb Devresinde 4 dk. Zn Devresinde 5 dk. kondisyon süresi uygulanmıştır. Sonuç olarak, %80.63 verim ile %55.13 Pb ve %77.60 verim ile %37.32 Zn kazanılabileceği görülmüştür.

Determination of optimum flotation conditions in Niğde (Ulukışla) complex Pb-Zn ore

Abstract

In this study, optimum flotation conditions of Pb-Zn complex ore from Niğde-Ulukışla region were investigated. The liberalization grain size (d80) of the ore sample to be used in experimental studies was determined and mineralogical analyzes were performed. Flotation experiments were performed at 30% solid ratio, 10 L/min air flow rate, 1250 rpm stirring speed and pH=9. Reagents and their amounts were determined in grinding, Pb and Zn rough flotation circuits. 8 minutes in the grinding circuit, 4 min in Pb Circuit and 5 min in Zn circuit were applied to in the experiments. As a result, The lead grade of lead concentrate for 55.13%, the recovery for 80.30%, and zinc grade of zinc concentrate for 37.32%, the recovery for 77.60% were obtained.
