Chemical durability of sintered glass-composite prepared from glass cullet and waste foundry sand
(Metallurgical & Materials Engineering, 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 ...
Solvent extraction and entrainment problem
(Association of Metallurgical Engineers of Serbia, 2020)
Applications of solvent extraction operations and processes play one of the most important roles in Hydrometallurgy. Therefore, in this brief review, some general concepts for selected representative applications are ...
The effect of cooling rate of slag from primary copper production in the valorization of copper in the flotation process
(Savez inženjera metalurgije Srbije, Beograd, 2015)
Technological procedure of slow cooling slag from primary copper production is applied in the purpose of copper recovery in the level of 98.5% to blister. This technological procedure is divided into two phases, first slow ...
Effect of process parameters on the phase transformation kinetics in copper-based alloys and composites
(Metallurgical & Materials Engineering, 2020)
Copper-based alloys and composites, owing to their convenient properties, are being considered essential materials in various industries. Since copper possesses an ability to develop high corrosion resistance, putting it ...
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 ...
Influence of the fabrication process of copper matrix composites on cavitation erosion resistance
(Savez inženjera metalurgije Srbije, Beograd, 2017)
Copper matrix composites reinforced with ZrB2 particles were produced in two ways: by hot pressing (HP) and laser-sintering process. Powder mixture Cu-Zr-B was mechanically alloyed before densification processes. Variations ...
Treatment of dispersed iron-bearing raw materials and modeling of the protection systems against air-pollution
(Association of Metallurgical Engineers of Serbia, 2016)
Based on the analysis of the non-standard iron-bearing raw materials treatment process and the results of real composition measurements of the flue gas, the study of hazards by identification of harmful substances that ...
Some aspects of physical metallurgy of microalloyed steels
(Savez inženjera metalurgije Srbije, Beograd, 2019)
Some aspects of deformation, precipitation, and recrystallization behavior in medium carbon V-microalloyed and low carbon Nb/Ti-microalloyed steels are presented in the paper. Changes in microstructure are explained together ...
Integrated procedure for recycling and valorization of useful components from secondary raw materials based on hard metals
(Savez inženjera metalurgije Srbije, Beograd, 2017)
Wide application of hard metals requires increased consumption of their constituents. Their high cost and scarcity impose the need for finding new, both ecologically and economically justified ways for their production. ...
Investigation of copper(i) sulphide leaching in oxidative hydrochloric acid solution
(Savez inženjera metalurgije Srbije, Beograd, 2015)
Present work is focused on the copper (I) sulphide leaching with sodium chloride in hydrochloric acid solution and with introduction of gaseous oxygen. Chemical reactions of leaching and their thermodynamic probabilities ...
