N2 - Nanostructure forms of semiconductor materials are of great interest. Among these compounds, copper sulfide as a variable stoichiometric composition attracts considerable attention. In the present study, copper sulfide nanoparticles were synthesized biologically from a chalcopyrite concentrate mainly containing chalcopyrite (46%) and pyrite (23%). Firstly, the copper concentrate was bioleached using moderate thermophilice bacteria, then the pre grown fungus Fusarium oxysporum was added to the pregnant solution. Biosynthesized nanoparticles collected were collected and their characteristics were compared with the product derived from the pure copper sulfate solution. The characterization was performed by UV spectrometry, Fourier Transform Infrared Spectroscopy (FTIR), Energy Dispersive X-ray Spectroscopy (EDS), Thermogravimetry (TG), Differential Scanning Calorimetry (DSC), Mass Spectrometry (MS), and Transmission Electron Microscopy (TEM). Finally, it was proven that the produced nanoparticles consisted of covellite and their size was about 5-40 nm.
