Ni-pd/al(2)o(3) catalyst supported on reticulated ceramic foam for dry methane reforming
(Savez inženjera metalurgije Srbije, Beograd, 2015)
In the present study, Ni-Pd/Al2O3 catalyst supported on alpha-Al2O3 based foam was prepared and evaluated in the dry methane reforming process. Corresponding metal chlorides were deposited to the foam surface by impregnation ...
Chalcopyrite leaching in acid media: a review
(Savez inženjera metalurgije Srbije, Beograd, 2020)
In the modern practice of copper production, more attention is increasingly being given to the possibility of treating low-percentage sulphide ores that cannot be treated with conventional procedures (crushing, grinding, ...
Semi-empirical software for the aluminothermic and carbothermic reactions
(Savez inženjera metalurgije Srbije, Beograd, 2014)
Understanding the reaction thermochemistry as well as formatting the empirical data about element distribution in gas-metal-slag phases is essential for creating a good model for aluminothermic and carbothermic reaction. ...
The process of obtaining quartz sand size fraction -0.4
(Savez inženjera metalurgije Srbije, Beograd, 2019)
The paper presents the process of quartz sand processing from the "Bijela Stijena" - Skocic deposit in the plant "Kesogradnja d.o.o." at Kozluk near Zvornik, Republic of Srpska. Bearing in mind the fact that this quartz ...
Review of the past, present, and future of the hydrometallurgical production of nickel and cobalt from lateritic ores
(Savez inženjera metalurgije Srbije, Beograd, 2020)
Laterite ores are becoming the most important global source of nickel and cobalt. Pyrometallurgical processing of the laterites is still a dominant technology, but the share of nickel and cobalt produced by the application ...
The use of electromagnetic field in designing the high qualityal-alloys for hot forging process
(Savez inženjera metalurgije Srbije, Beograd, 2014)
This work presents a way to obtain the better quality of EN AW 7075 aluminum high-strength alloy by application of electromagnetic field (EMF) during the casting process. In this way, the uniform fine-grained microstructure, ...
Complex sulphide-barite ore leaching in ferric chloride solution
(Savez inženjera metalurgije Srbije, Beograd, 2016)
The results of research on the leaching process of complex sulphide- barite ore were presented in this paper. The leaching process was carried out in a laboratory autoclave by ferric chloride solution. Considering that ...
Investigation of the optimal technology for copper leaching from old flotation tailings of the copper mine Bor (Serbia)
(Savez inženjera metalurgije Srbije, Beograd, 2020)
This work aimed to investigate optimal leaching technology for copper extraction from old flotation tailings of the Copper Mine Bor. The leaching degree of copper after leaching with sulphuric acid at 80 degrees C was 50%, ...
Reaction mechanism and kinetics of sulfide copper concentrate oxidation at elevated temperatures
(Savez inženjera metalurgije Srbije, Beograd, 2017)
Sulfide copper concentrate from domestic ore deposit (Bor, Serbia) was subjected to oxidation in the air atmosphere due to a better understanding of reaction mechanism and oxidation of various sulfides present in the copper ...
Chemical durability of sintered glass-composite prepared from glass cullet and waste foundry sand
(Savez inženjera metalurgije Srbije, Beograd, 2021)
In this study, the glass-composite was prepared using glass cullet and waste foundry sand as raw materials. The powder technology route was employed. The mixtures containing 10-50 wt% of the sand were sintered at T = 750 ...
