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.
In this study, the optimum floating conditions of the Pb-Zn complex coal of the Niğde-Ulukışla area were studied. The release one size (d80) of the cider sample that will be used in experimental studies has been determined and minerological analyses have been carried out. Floating experiments, 30 percent, 10 l/min. The speed of air flow is 1250 gigs/min. It is performed at the mixing rate and pH = 9. The reactors and quantities required to be used in the pipe, Pb and Zn crude floating circuit are determined. In experiments, 8 minutes in the bulking cycle, 4 minutes in the Pb cycle. 5 in the ZN circuit. Conditional time is applied. As a result, 80.63 percent efficiency with 55.13 percent Pb and 77.60 percent efficiency with 37.32 percent Zn could be achieved.
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.
