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 ...
Circular economy implementation in the development of fire-retardant materials used in construction, industry, and general-purpose products
(Savez inženjera metalurgije Srbije, Beograd, 2022)
During a fire, passive fire protection systems are designed to prevent the spread of flames, smoke, and toxic gases. The new fire-retardant (FR) material, used for passive fire protection, is created by combining copolymers ...
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 ...
Physico-chemical characterization of archaeometallurgical findings from two localities near Bor (Serbia)
(Savez inženjera metalurgije Srbije, Beograd, 2012)
Bor and its surroundings are well known for long and rich tradition in mining and metallurgical activities, as well as by numerous archaeometallurgical localities. The results of investigation of archaeometallurgical ...
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%, ...
