Abstract
In this study, the dissolution of copper sulfide minerals by the ferric (FeCl3) and ferrous (FeCl2) chloride leaching for upgrading the content of molybdenum disulfide (MoS2) in a molybdenite concentrate was investigated. The effect of various parameters was studied on the copper dissolution behaviour from the concentrate. In this matter, the copper dissolution was reached 94.84 % under the optimized leaching conditions. The kinetics of copper dissolution from the concentrate was established using a shrinking core model (SCM), and the process was controlled by diffusion, with a corresponding activation energy of 18.63 kJ mol-1 at the temperature range of 343–373 K. The amount of copper in the leachate was tested by the inductively coupled plasma-optical emission spectrometer (ICP-OES) and the solid phase was studied by X-ray diffraction (XRD), and scanning electron microscope (SEM). Results of the experiments show that the content of MoS2 in the solid residue was increased up to 88.59 % after the leaching.
