Determination of optimum flotation conditions in Nigde (Ulukisla) complex Pb-Zn ore

Abstract

In this study, optimum flotation conditions of Pb-Zn complex ore from Nigde-Ulukisla region were investigated. The liberalization grain size (d(80)) 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.
