Ispitivanje posledica prisustva urana u vodi za piće iz individualnih bunara u selu Dubravica u Braničevskom okrugu po zdravlje stanovništva / Testing the effects of the presence of uranium in drinking water from individual wells in the village of Dubravica in the Braničevo district on public health
(Univerzitet u Beogradu - Poljoprivredni fakultet, Beograd, 2021)
Selo Dubravica se delimično nalazi iznad zapadnog lignitskog ležišta Kostolačkog basena. Ispitivanjem suvog ostatka dobijenog iz vode za piće iz dva individualna bunara rendgenskom difrakcionom analizom, na osnovu ...
Metal accumulation in populations of Calamagrostis epigejos (L.) Roth from diverse anthropogenically degraded sites (SE Europe, Serbia)
(Springer, Dordrecht, 2018)
Heavy metal accumulation is recognized as a very important global pollution problem in the last decades. Plant species have been recognized as natural bioindicators of environmental pollution, especially the amount of heavy ...
Investigations of quartz raw materials from the locality of Rekovac muncipality
(Savez hemijskih inženjera, Beograd, 2019)
Quality of raw materials, including quartz sand and quartzite, varies from one deposit to another. Furthermore, the material quality determines in which industrial branches it can be used after certain preparation processes. ...
Effect of Delamination on Physico-Chemical Properties of Kaolin
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2021)
To provide the quality required for its use, raw kaolin must be subjected to certain processing procedures like delamination which is applied to the layered structure materials. The aim of this research is to determine the ...
Thermally Induced Phase Transformation of Mn - LTA and Mn-FAU Zeolite to Anorthite Phases
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2021)
Data on thermally induced transformations of Mn exchanged zeolites LTA and FAU topology are presented in this paper. Thermally induced phase transformation of Mn-exchange zeolites are followed in the range from 700 to 1300 ...

(Mineralogical Soc, Twickenham, 2020)
Two samples collected from the phosphogypsum deposits of the chemical products industry Elixir Prahovo (Serbia) were subjected to a recrystallization experiment performed over several repeated cycles. In these tests, ...
Thermal analysis and phase changes of mechanochemically activated sodium carbonate
(Elsevier, Amsterdam, 2022)
Sodium carbonate is a well-known material for being used as a good sorbent of carbon dioxide from the atmosphere, and as such has gained increasing importance in environmental protection. In order to enhance its sorption ...
Investigation of mechanism and kinetics of chalcopyrite concentrate oxidation process
(Croatian Metallurgical Society, 2008)
The oxidation process of chalcopyrite concentrate "Rudnik" (Serbia) was investigated by DTA-TG measurements under air conditions in the temperature range of 298 - 1173 K, as well as by XRD analysis of the oxidation products ...
Prediction models of non-ferrous secondary raw materials formation
(University of East Sarajevo, Faculty of Technology, 2013)
For the prediction of formation of non-ferrous processing and accumulating waste both model of balancing and model of correlation and regression analysis can be employed, while the dynamic model can be applied only for the ...
A Kinetic Study of Limestone Dry Micronization in an Ultra-Centrifugal Mill with Peripheral Comminuting Path
(Goller Verlag Gmbh, Baden Baden, 2017)
Because of its physico-mechanical and physico-chemical characteristics, fine-ground (i.e. micronized) limestone is widely applied in the production of new materials. Limestone can be used as a filler, coating and/or powder ...
