  • Crystallography and Surface Oxidation of Stoichiometric Arsenopyrite from Šumadija-Kopaonik Pb-Zn/Polymetallic Ore District (Serbia)

    Ivana Jelić, Aleksandar Pačevski, Aleksandar Kremenović, Aleš Šoster, Andreja Šestan, Janez Zavašnik (2023)
    The behaviour and stability of arsenopyrite largely depend on its crystal structure, but studies of crystallography and structural defects are scarce. For clarification, we investigated a series of natural arsenopyrite crystals from the polymetallic Pb-Zn-(±Cu,Ag,Au,Sb,Bi,W) Šumadija-Kopaonik ore district (Serbia) by powder X-ray diffraction (XRPD). Among them, samples from the Drenjak gold mineralisation showed near-stoichiometric FeAsS composition and were further investigated by conventional and high-resolution transmission electron microscopy methods. TEM revealed abundant planar crystallographic defects and epitaxial surface oxide layer ...

  • Arsenopirit iz rudnih ležišta Šumadijsko-kopaoničke oblasti: paregeneza, sastav i produkti oksidacije

    Ivana N. Jelić (2023)
    Arsenopirit, FeAsS je čest pratilac polimetaličnih orudnjenja Šumadijsko-kopaoničke oblasti. Jedan je od sulfida koji u najvećoj meri koncentriše zlato. Nepoželjan je u rudama jer njegovom oksidacijom na jalovištima može doći do oslobađanja arsena koji spada u elemente toksične za životnu sredinu. U okviru ovog doktorata sistematski su ispitivani arsenopiriti iz različitih stadijuma i tipova orudnjenja rudnih ležišta i mineralizacija Šumadijsko-kopaoničke oblasti (Rudnik, Sastavci, Trepča, Gokčanica – Drenjak i Rujak, Golijska reka i Jurija). Uzorci arsenopirita ispitivani su polarizacionom mikroskopijom ...
