Abstract

The importance of molybdenum deposits has been increased in Turkey as well as the molybdenum industry in the world. In this context, the aim of this study was to evaluate the flotation behavior of low-grade porphyry copper-molybdenum ore obtained from the Kirklareli region of Turkey. The ore sample used in this study contained 0.18% Mo and 0.15% Cu. In this study, the effect of several parameters such as particle size, pH, types and amounts of collector, depressant, and frother on the flotation were investigated. Based on the results obtained from this study, gas oil as collector, pine oil as frother, and sodium sulphide as depressant at pH 12 were found to be optimum parameters for the flotation of molybdenite ore. Meanwhile, the kinetics of batch flotation behavior of the molybdenum ore was obtained by applying the first order and second order kinetics models. The results indicated that the flotation rate constant responds to second-order kinetics model with correlation coefficient of 0.99. At the end of the multi stage flotation test performed under the optimum flotation parameters, Mo recovery and content for final concentrate were found as 72.3% and 52.15%, respectively.
