Niðde (Ulukýþla) kompleks Pb-Zn cevherinin optimum flotasyon þartlarýnýn belirlenmesi

Bu çalýþmada, Niðde-Ulukýþla yöresine ait Pb-Zn kompleks cevherinin optimum flotasyon þartlarý araþtýrýlmýþtýr. Deneysel çalýþmalarda kullanýlacak olan cevher numunesinin serbestleþme tane boyutu (d80) belirlenmiþ ve mineralojik analizleri gerçekleþtirilmiþtir. Flotasyon deneyleri, %30 katý oranýnda, 10 L/dk hava akým hýzýnda, 1250 dev/dk karýþtýrma hýzýnda ve pH=9’da gerçekleþtirilmiþtir. Öðütme, Pb ve Zn kaba flotasyonu devresinde kullanýlmasý gerekli olan reaktifler ve miktarlarý belirlenmiþtir. Deneylerde, öðütme devresinde 8 dakika, Pb Devresinde 4 dakika, Zn Devresinde 5 dakika kondisyon süresi uygulanmýþtýr. Sonuç olarak, %80.63 verim ile %55.13 Pb ve %77.60 verim ile %37.32 Zn kazanýlabileceði görülmüþtür.

Determination of optimum flotation conditions in Niðde (Ulukýþla) complex Pb-Zn ore

In this study, optimum flotation conditions of Pb-Zn complex ore from Niðde-Ulukýþla 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 minutes in Pb Circuit and 5 minutes 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.
