Formation and development of damage of basalt under the effect of cavitation / Nastajanje i razvoj oštećenja bazalta pod dejstvom kavitacije
(Engineering Society for Corrosion, Belgrade, Serbia, 2019)
The paper examines the cavitation resistance of the cast basalt samples. Samples were obtained by melting, casting and thermal treatment of crushed basalt rocks from the Vrelo Kopaonik deposit. The experiment was conducted ...
Comparison of the formation and development of cavitation damage on cast and sintered samples based on basalt / Poređenje nastajanja i razvoja kavitacionih oštećenja livenih i sinterovanih uzoraka na bazi bazalta
(University of Belgrade, Technical Faculty, Bor, 2019)
The paper examines the resistance to the effect of cavitation of glass-ceramics based on basalt. Two types of samples were investigated: cast and sintered samples based on basalt.The cavitation erosion test was performed ...
Quality, sources and balancing of iron and steel scrap / Kvalitet, izvori i bilansiranje otpadaka gvožđa i čelika
(Savez inženjera i tehničara Srbije, Beograd, 2015)
Besides iron ore, the main raw material of iron and steel production is steel scrap. This paper presents the quality and sources of creation the iron and steel scrap and estimation of their creation in the future. The ...
Leaching of chalcopyrite concentrate by hydrogen peroxide in sulphuric acid solution / Luženje halkopiritnog koncentrata rastvorom sumporne kiseline i vodonik-peroksida
(Savez inženjera i tehničara Srbije, Beograd, 2019)
Due to complex mineralogy and/or low content of base metals, some ores and mineral concentrates are not suitable for pyrometallurgical treatment. Therefore, those ores and concentrates have to be treated by application of ...
Estimation of GHG emission in Serbia for period 1995-2013 using recurent neural networks / Emisije gasova staklene bašte u Srbiji za period 1995-2013. godina primenom rekurentnih neuronskih mreža
(Naučno-stručno društvo za zaštitu životne sredine Srbije - Ecologica, Beograd, 2015)
The aim of this work was to create an ANN model for the prediction of GHG emissions in the Republic of Serbia in the period 1995-2013. Because of the lack of GHG emission data and inputs for Serbia, the ANN model was ...
