The recycling of high magnesium aluminum alloys estimation of the most reliable procedure
(Savez inženjera metalurgije Srbije, Beograd, 2009)
Aluminum is one of the most recyclable materials. Namely, the properties of aluminum are not affected by the recycling and reuse, thus enable that high value of the metal is maintained after reprocessing. The re-smelting ...
The influence of thermomechanical treatment on recrystallization of AlMg4.5Cu0.5 alloy
(Savez inženjera metalurgije Srbije, Beograd, 2007)
Recrystallization behavior of an Al-Mg-Cu alloy (4.5 wt. %Mg and 0.45 wt %Cu) subjected to different thermomechanical treatments (TMTs) have been studied by means of light optical microscopy and hardness measurements. In ...
Hydrometallurgical recovery of tin and lead from waste printed circuit boards (wpcbs): limitations and opportunities
(Croatian Metallurgical Soc, Zagreb, 2016)
In this paper, possibility for selective Pb and Sn recovery, using three different solutions of NaOH, HCl and HNO3, from WPCBs containing low concentrations of Pb and Sn is presented. According to obtained results, over ...
Optimisation of ferriferous dust and mud preparation acts from iron and steel production on purpose of returning to primary processes / Optimizacija postupaka pripreme železonosnih prašina i muljeva iz proizvodnje gvožđa i čelika u cilju vraćanja u primarne procese
(Savez inženjera metalurgije Srbije, Beograd, 2004)
In this paper detailed characterization of ferriferous dust and mud which originated from aglomerization, blast- furnace and converter process in Iron-works Smederevo were shown. Optimization of method peletization was ...
Experimental and numerical evaluation of a steamline behaviour using local approach
(Croatian Metallurgical Society, 2007)
Results of the experimental and numerical comparative analysis of steamline pipes have been presented. New pipes and the pipes used for more than 117,000 hours at 540 degrees C under pressure of 42 bars have been simultaneously ...
A two-stage metal valorisation process from electric arc furnace dust (eafd)
(Croatian Metallurgical Soc, Zagreb, 2016)
This paper demonstrates possibility of separate zinc and lead recovery from coal composite pellets, composed of EAFD with other synergetic iron-bearing wastes and by-products (mill scale, pyrite-cinder, magnetite concentrate), ...
A model for predicting fracture toughness in overaged 7000 alloy forgings
(Savez inženjera metalurgije Srbije, Beograd, 2007)
An attempt to develop a multiple micromechanism-based model for predicting plane-strain fracture toughness, KIc, of overaged 7000 alloy forgings has been made. The proposed model reveals the quantitative relations between ...
Properties of Cu-Al2O3 Powder and Compact Composites of Various Starting Particle Size Obtained by High-Energy Milling
(Savez inženjera metalurgije Srbije, 2009)
Copper-based composites were obtained using high energy milling. The inert gas-atomized prealloyed copper powder (average particle size - 30 μm) containing 2 wt.% Al, and the mixture of electrolytic copper powder (average ...
Fuel consumption analysis in cooper melting and refining plants / Analiza potrošnje energenata u pogonima za topljenje i rafinaciju bakra
(Savez inženjera metalurgije Srbije, Beograd, 2004)
Cathode cooper production and refining include significant consumption of almost all-conventional fuel types. The given consumption is high in specific and in nominal way. Especially high fuel value content is on Cathode ...
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 ...
