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), ...
Synthesis and sintering of Cu-Al2O3 nanocomposite powders produced by a thermochemical route
(Savez inženjera metalurgije Srbije, Beograd, 2007)
By hydrometallurgy and powder metallurgy along with prognosis of physical-chemical properties, a synthesis of new improved materials can be successfully performed with in advance pre-set properties which is conditioned by ...
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 ...
Tensile properties of fiber-resin composites that consist of polyarmid fiber (Kevlar 129) and poly(vinilbutyral) / Zatezna svojstva polimernog kompozitnog materijala poliaramidna vlakna (Kevlar 129) - poli(vinilbutiral)(PVB)
(Savez inženjera metalurgije Srbije, Beograd, 2006)
Thanks to fact that composite material have usefully characteristic two or more materials, they are becoming more and more substitute standard materials in every field of technique they start to. In this study static ...
Characterization of nano-powder morphology obtained by ultrasonic spray pyrolysis
(Savez inženjera metalurgije Srbije, Beograd, 2008)
Spherical nanosized particles of copper were synthesized by ultrasonic dispersion of solutions from copper sulphate in the temperature range of 800-900°C in hydrogen atmosphere. A controlled particle size was realized ...
