The Kovin lignite is characterized by high moisture content, medium to high ash yield, medium to high sulphur content and a relatively low gross and net calorific value. The mineralogical composition, and major and trace element contents were determined by X-ray diffraction, scanning electron microscopy with energy dispersive Xray spectroscopy (SEM-EDS) analyses, and inductively coupled plasma optical emission spectrometry (ICP-OES). ......

Determining the Availability of Continuous Systems at Open Pits Applying Fuzzy Logic
This work presents a model for determining the availability of continuous systems at open pits by applying fuzzy logic and fuzzy inference systems. The applied model was formed by the synthesis of independent partial indicators of availability. The model is based on an expert system for assessing the availability of continuous mining systems. The availability of the system, as a complex state parameter, is decomposed into the partial indicators, reliability, and convenience of maintenance, and the fuzzy compositions, used ...системи, континуални систем експоатације, површински коп, рударство, расположивост, фази логика, max–min композиција, min–max композицијаMiljan Gomilanović, Miloš Tanasijević, Saša Stepanović.

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.

Prognozna ocena resursa kaolinitskih glina u sedimentnim basenima Srbije
Vladimir M. Simić (2003)Kaolinitske gline predstavljaju jednu od privredno najznačajnijih nemetaličnih mineralnih sirovina u Srbiji. Ležišta tih glina odavno se istražuju i eksploatišu u Aranđelovačkom i Kolubarskom basenu i basenima vlašićkog antiklinorijuma. Osim toga, u većem ili manjem obimu istražene su mnoge lokalnosti, a na nekima od njih vršila se povremena eksploatacija. Dosadašnja istraživanja kaolinitskih glina imala su, međutim, prevashodno uzak istraživački cilj - utvrđivanje rezervi glina određenog ležišta, dok su istraživanja regionalnog karaktera bila malog obima i vezana za delove pojedinih ...prognozna ocena, resursi kaolinitskih glina, sedimentni baseni, Srbija, geologija, mineralogija, kvalitet, potencijalnostVladimir M.
