Due to depleting metallic sulfides, metallic oxides are gaining importance as alternative sources of commodities such as lead and zinc. Flotation might be anticipated as a promising solution for the processing of metallic sulphides provided that detailed characterization work and investigation on fundamental aspects are conducted. In this work, mineralogical, chemical and thermal characterization of Kayseri-Develi Pb-Zn ore is done. Mineralogical work using polarized microscopy, showed that the major minerals in this particular ore are cerussite (PbCO3) and smithsonite (ZnCO3). Chemical analyses using Atomic Absorption Spectroscopy (AAS) and X-ray Fluorescence (XRF) revealed a Zn grade of 32.70 % and a Pb grade of 11.70 %. The thermal characteristics and behaviour of the ore were retained using Thermogravimetry/Differential Tthermogravimetry (TG/DTG) and Differential Scanning Calorimetry (DSC). The TG/DTG profile of the ore revealed that the ore reaches the maximum extent of decomposition at 383.42 °C under inert conditions, corresponding to approximately 20 % weight loss. TG/DTG and DSC profiles demonstrate characteristic peak positions for weight loss and heat flow, respectively, occurring at almost identical temperature values. Further, the calcination reaction region identified in the TG/DTG profile was reflected by an endothermic heat flow region in the DSC profile of the ore.
