AB  - Modern industrial product design implies presence of many different materials. Consequently, in the recycling process, shredding and separation procedures are applied. However, all materials cannot be completely separated; therefore, there is a contamination in the recycling streams. The quality of the materials streams can be reduced in each of the following recycling steps. These qualitative losses cannot be described by material balance. This paper presents the concept of exergy as a measure of quality losses, and gives the methods for the calculation of the exergy content and the exergy loss. Losses attributed to the recycling or material losses, material contamination losses and dilution requirements can be used as indicators for the materials quality loss as well as for the resource efficiency in the production systems. In this paper, the example of calculations on the steel scrap is presented.
AB  - Dizajn modernih industrijskih proizvoda je takav da oni predstavljaju kompleksne spojeve različitih materijala.

Zbog toga se kvalitet materijala može smanjivati u svakom narednom reciklažnom koraku.

AB  - 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 those minerals are represented in complex structural-textural relationships, it is not possible to extract lead, zinc and copper minerals from ore by flotation methods. The obtained results confirmed possibility of the ore processing directly, by chemical methods. The effect of temperature, time and oxygen partial pressure on the lead, zinc and copper dissolution was studied. The maximal leaching degree was achieved at 100 °C and amount of 91.5 % for Pb, 96.1 % for Zn and 60.7 % for Cu). Leaching at temperatures above 100 °C is impractical.

AB  - Wastewaters produced by mining and metallurgical treatment of polymetallic sulfide ores have polluted the Timok River in Serbia for more than 100 years. We have characterized seven different wastewater streams within the RTB Bor facilities, investigating their influence on pollution of the Timok River before its confluence with the Danube River. Their relative contribution was calculated by considering the contaminant load of each wastewater stream and non-conservative transport along their flow paths. Three sampling spots in the Timok River, before and after its confluence with the Borska River, were also monitored.

Chemical reactions of leaching and their thermodynamic probabilities are predicted based on the literature data and products which were formed during the process and the overall leaching reaction was defined. The influence of temperature and time on the leaching degree of copper was experimentally determined. The quantity of dissolved copper increases with the increase of both investigated parameters. Elemental sulphur was formed as the main leaching product, precipitated at the particle surfaces and chloride ions have a role to disrupt the creation of this passive layer.

AB  - Materials for recycling always contain a certain degree of contamination. The presence of impurities i.e. contamination in the recycling streams causes a change in the composition of the original materials to recycle. As a result, the quality of materials can be reduced in each successive step of recycling. In addition, the resources of lower quality are produced from the resource flows which had a higher quality in their original form. This kind losses of quality cannot be measured by mass balance, as well as the quality degradation not only can display measurements of mass. For the calculation of all losses caused by recycling contaminations, all further recycling processes required to return the materials back into resource cycles must be included. The method for calculating the exergy content and exergy losses of metal solutions during recovery and recycling is presented in this paper. The losses attributed to recycling, namely the material losses, the contamination losses with other metals, and the consequent need for dilution can be used as indicators of the quality loss of materials and of the efficiency of resource use in product systems. Therefore, exergy is proposed here as a measure of the efficiency of resources use. This paper presents calculations of exergy losses during recycling shown in the case of aluminum waste.
AB  - Materijali za recikliranje uvek sadrže izvestan stepen nečistoća. Prisustvo nečistoća tj. kontaminacija u reciklažnim tokovima izaziva promenu u izvornom sastavu materijala za reciklažu. Usled toga, kvalitet materijala može se smanjivati u svakom narednom koraku reciklaže. Pored toga, resursi nižeg kvaliteta proizvedeni su iz resursnih tokova koji su u izvornom obliku imali viši kvalitet. Ovakvi gubici kvaliteta ne mogu da se mere masenim bilansima, isto kao što se degradacija kvaliteta ne može prikazati samo merenjem mase. Za proračun svih gubitaka prouzrokovanih reciklažnom kontaminacijom, svi dalji procesi reciklaže potrebni da bi se materijali vratili nazad u resursne cikluse moraju biti uključeni. U ovom radu prikazan je metod za izračunavanje eksergijskog sadržaja i eksergijskog gubitka metalnih rastvora u toku iskorišćnja i reciklaže. Gubici pripisani reciklaži ili tačnije materijalni gubici, gubici usled kontaminacije drugim metalima i posledično potreba za razblaživanjem, mogu se koristiti kao indikatori gubitka kvaliteta materijala i efikasnosti korišćenja resursa u proizvodnim sistemima. Dakle, ovde je eksergija predložena kao mera efikasnosti korišćenja resursa. U radu su proračuni eksergijskih gubitaka tokom reciklaže prikazani na primeru aluminijumskog otpada.

Za proračun svih gubitaka prouzrokovanih reciklažnom kontaminacijom, svi dalji procesi reciklaže potrebni da bi se materijali vratili nazad u resursne cikluse moraju biti uključeni. U ovom radu prikazan je metod za izračunavanje eksergijskog sadržaja i eksergijskog gubitka metalnih rastvora u toku iskorišćnja i reciklaže. Gubici pripisani reciklaži ili tačnije materijalni gubici, gubici usled kontaminacije drugim metalima i posledično potreba za razblaživanjem, mogu se koristiti kao indikatori gubitka kvaliteta materijala i efikasnosti korišćenja resursa u proizvodnim sistemima. Dakle, ovde je eksergija predložena kao mera efikasnosti korišćenja resursa. U radu su proračuni eksergijskih gubitaka tokom reciklaže prikazani na primeru aluminijumskog otpada.",

AB  - Lead - free soldering became very popular in the whole world, because of high ecological demands in industry. Most of alternative alloys have high content of tin, and some of them are already used in electronic industry. One of them is Ag-Sn. In order to decrease melting point of alloy, addition of indium is used and it is expected that Ag-In-Sn alloy will be suitable for replace Sn-Pb standard solder alloy. From that reasons, the results of investigation thermodynamic properties and phase equilibria of Ag-In-Sn alloys are presented in this paper. The investigated samples are with constant molar ratio of In:Sn = 1:2. DTA and SEM analysis were used as methods for characterization of Ag-In-Sn ternary alloys, and the GSM model was used as a method for thermodynamic prediction of Ag-In-Sn alloys at 1423 K.
AB  - Jedan od aktuelnih svetskih trendova, obzirom na primarne ekološke zahteve svakako je i pronalaženje novih, bezolovnih lemnih legura koje mogu zameniti već postojeće lemove na bazi olova. Legure koje se već koriste u elektronskoj industriji kao zamena za standardne Pb-Sn lemove, imaju veliki sadržaj kalaja (Ag-Sn), pa se može očekivati da će se dodatkom indijuma kao trećeg elementa sniziti temperatura topljenja legure. Iz tih razloga, ispitivan je sistem Ag-In-Sn, pri čemu su odabrane legure sa konstantnim molskim odnosom In:Sn = 1:2. U cilju što potpunijeg poznavanja termodinamičkih veličina, kao i faznih ravnoteža ovog sistema, rad obuhvata sledeće: • Kvalitativnu diferencijalnu termijsku analizu (DTA), u cilju određivanja karakterističnih temperatura faznih transformacija za ispitivane legure • Skenirajuću elektronsku mikroskopiju (SEM) radi utvrđivanja mikrostrukture uzoraka • Određivanje koeficijenata aktivnosti, aktivnosti, parcijalnih i integralnih molarnih termodinamičkih veličina legura sistema Ag-In-Sn, na temperaturi od 1423 K metodom termodinamičkog predviđanja po opštem modelu rastvora.

AB  - Simultaneous extraction of copper and indium with chelate extractants (LIX84 and D2EHPA) was
described. Stechiometry of metal-organic complexes examined using the method of equimolar ratios resulted in
CuR2 and InR3 forms of hydrophobic extracting species. A linear correlation was obtained between logarithm of
distribution coefficients and chelate agents and pH, respectively. Selectivity is generaly higher with higher
concentrations of chelate agents in the organic phase, and is decreased with increase of concentration of
hydrogen ions in feeding phase.
