Abstract:
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 concentratemainly containing chalcopyrite (46%) and pyrite (23%). Firstly, the copper contents of the concentrate were bioleached using thermophile bacteria, then the grown Fusarium oxysporum was added to the prepared solution and the biosynthesized nanoparticles collected and their characteristics 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), Thermogravimetery (TG), Differential Scanning Calorimetery (DSC), Mass Spectrometery (MS), and Transmission Electron Microscopy (TEM). Finally, it wasproved that the produced nanoparticles had a covellite composition and their size was about 5-40 nm.
