The Muteh gold deposit (NE of Golpaygan) in the central part of intrusive-metamorphic belt of Sanandaj-Sirjan zone comprises NW-SE trending gold-quartz vein occurred in metamorphic complex. Gold mineralization is associated with quartz veins that formed during regional deformation across the mylonitic zones in metamorphic rocks of predominantly meta-volcanic, gneiss and schist. The sulfidation ...

We present a comprehensive device model for Cu(In,Ga)Se2 (CIGSe) thin-film solar cells based on numerical SCAPS-1D simulations. The reproduces the experimentally determined current-voltage and capacitance-voltage characteristics of Rb-free reference device, sample that underwent an RbF-treatment, CIGSe/RbInSe2-stack. According to this model, in agreement with experimental findings, main consequ...

Porphyry-type deposits are the major sources of copper and molybdenum, flotation has been adopted to recover them separately. The conventional reagents used for depressing minerals, such as NaHS, Na2S, Nokes reagent, have potential emit toxic H2S gas when pulp pH was not properly controlled. Thus, in this study applicability microencapsulation (ME) using ferrous phosphate ions an alternative pr...

Cyclic voltammetry and potentiodynamic polarization analyses were utilized to investigate the mechanism kinetics of glycine leaching reactions for chalcopyrite. The effects pH (9–12), temperature (30–90 °C) concentration (0–2 mol/L) on corrosion current density, potential cyclic voltammograms investigated using chalcopyrite concentrate–carbon paste electrodes. Results showed that an increase in...

Abstract Chalcopyrite solar cells will have to play an important role mitigate the climate crisis, because of their particularly low carbon emissions. Doping in these semiconductors is due native defects and intentional alkali impurities. The recent progress efficiency has been made possible by post-deposition treatments with heavy alkalis. Tail states band gap distribution are main limitations...
