AB  - This paper presents thermochemical synthesis of copper/alumina nanocomposites in a Cu-Al2O3 system with 1–2.5 wt.% of alumina and their characterization, which included: transmission electron microscopy: focused ion beam (FIB), analytical electron microscopy (AEM) and high resolution transmission electron microscopy (HRTEM). Thermodynamic analysis was used to study the formation mechanism of desirable products during drying, thermal decomposition and reduction processes. Upon synthesis of powders, samples were cold pressed (2 GPa) in tools dimension 8 × 32 × 2 mm and sintered at temperatures within the range 800–1000 °C for 15 to 120 min in a hydrogen atmosphere. Results of characterization showed that dispersion-strengthened compacts could be produced by sintering of thermo-chemically prepared Cu-Al2O3 powders with properties suitable for material application, such as a contact material exhibiting high strength and high electrical conductivity at the same time. Additional research was carried out in order to analyze the application of the obtained nanocomposite powders for the synthesis of copper/alumina nanocomposites by a new method, which is a combination of a thermochemical procedure and mechanical alloying. The measured values of an electric conductivity and hardness were compared with ones in literature, confirming an advantage of the proposed combined strategy.

AB  - This study presents the results of the theoretical assessment and a preliminary experimental investigation of technology metals (TM) recovery from magnetic fraction obtained after mechanical treatment of waste printed circuit boards (WPCBs). Experimental work included physical and chemical characterization, thermodynamic analysis, and pyrometallurgical tests corresponding to secondary lead, copper, and steel metallurgy. Technology metals recyclability and recovery potential were evaluated with respect to their distribution between metal and slag phase (difficult for recovering) versus the dust phase (easy for recovering). According to obtained results, it was determined that high-temperature processing of magnetic fraction in the electric arc furnace promotes volatilization of the TM and their pre-concentration in the filter as a dust product from which they could be valorized using further hydrometallurgical methods. © 2019, Association of Metallurgical Engineers of Serbia.

AB  - This paper presents sintered materials for use as contacts produced via novel synthesis method of
starting powders by combination of explored conventional routes of thermochemical synthesis and
mechanical alloying.
Starting raw materials for powder synthesis by thermochemical route were soluble salts, nitrates of
copper and aluminum of p.a. quality, dissolved in distilled water (50wt.% solution) in suitable ratio
for final powder to contain 50wt.% of Al2O3 in structure. Nitrate solution was spray dried and
subjected to heat treatment (900 ºC/1h). Obtained oxides were reduced in hydrogen atmosphere
(flow rate 20L/h at 350 °C for 1h) in order to obtain composite of Cu-Al2O3. Produced powders
were used for mechanical alloying of atomized copper (5h, 300 min-1). Final amount of alumina
Al2O3 in composite powder were 1, 1.5 and 2 wt.%. After mechanical alloying obtained powders
were compacted by a uniaxial pressing (8×32×3mm, 500 kN). Sintering of samples was performed
in hydrogen atmosphere in isothermal conditions at five different temperatures in the range from
725-925 °C for 15 to 120 min.
Results of characterization show, that increase of Al2O3 content has more noticeable effect on the
electrical conductivity and hardness than sintering temperature and time. With increase of Al2O3
from 1 to 1.5 wt.% there is a slight decrease in both investigated properties, while with increase up
to 2 wt.% Al2O3 significant decrease in electrical conductivity and hardness of sintered samples is
observed.
According to achieved results optimum sintering parameters for composite materials produced by
novel synthesis method based on copper with dispersed 1% Al2O3 are 875 ºC/60 min.
Based on the achieved results, this method provides production of contact materials with good
combination of electrical and mechanical properties, but with estimated lower production costs.

AB  - This research aimed to develop a novel catalyst based on WO3/ZrSiO4 system for halogenated hydrocarbons processing. The production method of this catalyst involved extrusion and as such was simplified compared to thermo-chemical synthesis routes. It had a reduced number of process stages and a lower environmental impact at the same time. In order to examine the phase composition of the catalyst after sintering at 800 °C, the XRD analysis was carried out. The catalyst was then tested in chlorodifluoromethane dehalogenation process on laboratory scale at temperatures of 300, 400 and 500 °C in the presence of water vapor. Catalyst achieves high dehalogenation efficiencies of 88.6, 95.9, and 99.5 % for each of the process temperatures, respectively. Obtained results are in the range with those achieved by using thermo-chemically prepared dehalogenation catalysts.

process of synthesis of tribological materials based on tin sulphides. The tin sulphides
powders were synthesized from selected precursors by pyrometallurgical
method in rotary tilting tube furnace. The thermodynamic parameters of the synthesis
were determined using HSC Chemistry software modelling package. In
addition, the synthesis process was also characterized by the thermal analysis
method: simultaneous differential scanning calorimetry and thermogravimetry
(DCS-TGA). The characterization of the synthesized tin sulphides powders included
analysis of chemical composition by optical emission spectroscopy, phase
composition identification by X-ray diffraction (XRD) and examination of morphology,
as well as elemental composition by scanning electron microscopy (SEM)
with energy-dispersive spectroscopy (EDS). The hexagonal SnS2 and orthorhombic
Sn2S3 phases were formed after the thermal treatment of starting powders in nitrogen
atmosphere. The obtained results indicate the positive effects of the graphite
addition which enables the synthesis of tin sulphide powders with appropriate
content of sulphide phases with minimal loss of sulphur.

AB  - The aim of this research was to study the effect of graphite addition in the process of synthesis of tribological materials based on tin sulphides. The tin sulphides powders were synthesized from selected precursors by pyrometallurgical method in rotary tilting tube furnace. The thermodynamic parameters of the synthesis were determined using HSC Chemistry software modelling package. In addition, the synthesis process was also characterized by the thermal analysis method: simultaneous differential scanning calorimetry and thermogravimetry (DCS-TGA). The characterization of the synthesized tin sulphides powders included analysis of chemical composition by optical emission spectroscopy, phase composition identification by X-ray diffraction (XRD) and examination of morphology, as well as elemental composition by scanning electron microscopy (SEM) with energy-dispersive spectroscopy (EDS). The hexagonal SnS2 and orthorhombic Sn2S3 phases were formed after the thermal treatment of starting powders in nitrogen atmosphere. The obtained results indicate the positive effects of the graphite addition which enables the synthesis of tin sulphide powders with appropriate content of sulphide phases with minimal loss of sulphur.

AB  - Reuse of waste is one of the main principles of sustainable development and circular economy. Secondary alkaline lead slag is a hazardous waste generated in the recycling process of lead-acid batteries that may be suitable in construction materials. The environmental impact of the use of lead slag as a partial replacement of fine aggregates in the cement-based stabilization/solidification (S/S) process for the preparation of concrete was studied in this paper. Solidified products containing 10%, 15%, 20%, and 25% slag were laboratory tested by unconfined compressive strength (UCS) analyses and the Toxicity Characteristic Leaching Procedure (TCLP). At the same time, the leachability of toxic elements from solidified products with a high percent of slag was evaluated under environmental conditions for during one year. The results of the UCS and TCLP indicated that utilization of this type of slag in cement-based applications may be justified with its controlled addition. However, the described application of the slag was disputed due to the high release of As under high alkaline environmental conditions. Eh-pH analyses and the geochemical modeling using the software PHREEQC were evaluated, as well as the mechanism of pollutant (Pb, As) immobilization (precipitation, adsorption) as a function of pH conditions.

AB  - Secondary alkaline lead slag (SALS), generated during lead–acid batteries recycling, is a hazardous waste due to its high reactivity, solubility, and migration of toxic elements. After pulverization caused by storage under atmospheric condition for 30 days, the SALS was sieved and coarse fraction (+ 1 mm) was returned to the recycling process. Finer fraction (− 1 mm) was treated by water leaching to remove soluble compounds. SALS compositions prior and after the pre-treatment and effects of liquid-to-solid ratio, stirring rate, and temperature on Na, S, Fe, As, and Pb leaching from SALS were analyzed. The results show that maximal leaching degrees were 95.78%, 75.32%, and 79.89% for Na, S, and As, respectively (20 l kg−1, 600 min−1, 333 K, 120 min). Leachability of Na and S from SALS was controlled by dissolution of Na2SO4 that could be recovered from leaching solution. Isothermal As leaching is described by diffusion mechanism with activation energy of 15.5 kJ mol−1. Insoluble Pb and Fe sulfates, sulfides, and oxides remained in the SALS. Pre-treated SALS, with reduced mass up to 32%, was solidified in cement matrix. The results of toxicity characteristic leaching procedure and unconfined compressive strength confirmed effectiveness of As removal from SALS by water leaching and Pb immobilization in cement matrix containing 20% of SALS.

AB  - This paper describes two stages process for synthesis of WS2 powder on selected temperatures by using WO3 as a precursor. WO3 submicron particles were prepared by ultrasonic spray pyrolysis of ammonium meta-tungstate (AMT) at 650°C in the air. WS2 particles were obtained by
sulfurization of the WO3 particles in presence of additive K2CO3 in a nitrogen atmosphere, first at
lower temperature (200°C) and followed by reduction at higher temperature (900°C). HSC Chemistry software package 9.0 is used for the analysis of chemistry and thermodynamic
parameters of the processes for synthesis of WS2 powder. The samples of WO3 and WS2 powders were characterized by X-ray diffraction (XRD) measurements. The morphology and composition
of these samples were examined by scanning electron microscopy (SEM) combined with energy
dispersive X-ray analysis (EDX).

AB  - This paper presents an experimentally-proved hydrometallurgical process for selective metals recovery from the waste-printed circuit boards (WPCBs) using a combination of conventional and time-saving methods: leaching, cementation, precipitation, reduction and electrowinning. According to the results obtained in the laboratory tests, 92.4% Cu, 98.5% Pb, 96.8% Ag and over 99% Au could be selectively leached and recovered using mineral acids: sulfuric, nitric and aqua regia. Problematic tin recovery was addressed with comprehensive theoretical and experimental work, so 55.4% of Sn could be recovered through the novel physical method, which consists of two-step phase separation. Based on the results, an integral hydrometallurgical route for selective base and precious metals recovery though consecutive steps, (i) Cu, (ii) Sn, (iii) Pb and Ag, and (iv) Au, was developed. The route was tested at scaled-up laboratory level, confirming feasibility of the process and efficiencies of metals recovery. According to the obtained results, the proposed hydrometallurgical route represents an innovative and promising method for selective metals recovery from WPCBs, particularly applicable in small scale hydrometallurgical environments, focused on medium and high grade WPCBs recycling.

AB  - Within the life cycle assessment, exergy analysis is one of the specific approaches to evaluate impacts on the environment through the quality of energy which is degraded during the production process [1]. Exergy can be described as a measure of resources depletion and it can be used to evaluate the process efficiency. Comparative assessment of product and processes through life cycle assessment is often used to identify the differences and environmental hotspots. This research applies exergy life cycle assessment to compare different Ni-based catalysts synthesis processes. In previous research [2,3] the authors compared novel Ni-Pd/Al2O3 catalyst synthesis processes with other ones from environmental and performance point of view. Idea of this research is to calculate the impacts on the environment by the total exergy consumption of Ni-based catalyst processes and to compare these results with the results from previous research. Compared with other Ni-based catalyst synthesis processes, the assessment results confirm the previous findings that the novel Ni-Pd/Al2O3 catalyst synthesis process has the smallest environmental impact. Furthermore, exergy life cycle assessment provided insight into impacts on the non-renewable and renewable resources.

AB  - In this research, catalytic properties of Ni-Pd/Al2O3 catalyst synthesized by aerosol impregnation
method were examined in the dry methane reforming process. First, reticulated ceramic foams
were impregnated by ultrasonically nebulized solution of corresponding chlorides and dried. The
catalyst was activated by direct hydrogen reduction, without calcination, at only 533 K. The
reforming test was carried out at temperatures of 873, 973 and 1023 K. Since CO and H2 are the
main products of the dry methane reforming, yields of those gasses were measured and obtained
results were a base for conclusions about selectivity, activity and stability of the catalyst.

AB  - Jarosite and neutral leaching residue (NLR) are the greatest environmental problems of hydrometallurgical zinc production due to their high quantity and hazardous content. Pyrometallurgical processes, such as the Waelz process, could be applied to recover valuable metals present in this waste. The paper investigates the possibility of forming environmentally stable Waelz slag after the Waelz process of jarosite and NLR. Waelz slag, obtained using CaO as a conventional alkaline additive in the Waelz process, showed high As and Sb release after the EN 12457-4 standard leaching test. Multiphase equilibrium composition calculations indicated that As and Sb were present as volatile and migratory species in the slag. In order to obtain Waelz slag with more stable matrices that would encapsulate and immobilize pollutants, MgO additions to CaO and different cooling conditions of the slag were further investigated. The efficiency of modification in additives composition and cooling conditions was assessed by EN 12457-4 leaching test and chemical and microstructural characterization (XRF and SEM-EDS analyses) of the Waelz slags. The results show that addition of MgO does not reduce the efficiency of the process, even more it increases leaching resistance of the slags. Concentrations of all investigated metals (As, Ba, Cu, Mo, Pb, Sb, Zn) after the leaching test were below defined limits for non-hazardous waste. Microstructural analyses revealed that MgO remained inert during Waelz process, and thus favoring the formation of amorphous stable structure, which was enhanced by increased cooling rate. All investigated Waelz slags with MgO additions are suitable for further use or safe disposal.

AB  - Technology advances have resulted in a growing demand for the new tribology materials. In development of the properties of tribology materials, improvements can be achieved by combining materials in form of composites. The aim of this work was production of solid lubricants composites based on sulfides of technology metals. Selected solid lubricant powders, tin sulfide (SnxSy) and tungsten disulfide (WS2), were synthesized by pyrometallurgical method in rotary tilting tube furnace (ST-1200RGV). The chemical thermodynamic parameters of the synthesis were determined using HSC Chemistry software modeling package. Characterization of the obtained powders included analysis of chemical composition by optical emission spectroscopy, phase composition identification by X-ray diffraction (XRD) and microstructural examination by the scanning electron microscopy (SEM) and energy-dispersive spectroscopy (EDS). Finally, the tribological properties of the as-synthesized powders in composite mixture were estimated. It has been shown the beneficial synergistic effect due to unique combination of properties between tin sulfides and tungsten sulfide in composite. In addition, advantage of synergistic tribology material (SnxSy/WS2) is simple method of synthesis and environmentally acceptable components of the composite.

AB  - In the current study it has been concluded that production of magnesium is only feasible by principles of closing the production cycle through optimization and synergy between primary and secondary magnesium production in order to generate as least as possible waste, emission and pollution in the Pidgeon process. The time of return of investment in redesign of secondary magnesium metallurgy was concluded to be 3.11 years which is the shortest time for this kind
of projects. The parameters as the individual discount rate 11.50%, internal rate of return, period of return 19%, positive net present value and profitability index 1.98 are acceptable. The unit capital cost per unit of $ 5,267/t and unit OPEX of $ 1,395/t were indicative of the economic success of this project and the most appropriate parameters have been achieved. Also, using gas as a fuel instead of coal will reduce OPEX for 8.4%. With this model waste substances are converted
into highly profitable resources along with the promotion of sustainability and a cleaner production strategy, which is the ultimate goal for company and society.

AB  - Ni-based catalysts supported on ceramics are particularly suitable for industrial applications, for instance reforming of hydrocarbons to produce synthesis gas or hydrogen and production of carbon nanofibers. Conventional synthesis processes for all metal/ceramic catalysts are impregnation, precipitation, coprecipitation and others. The authors have previously developed a novel process for the synthesis of Ni-based catalysts supported on reticulated ceramic foams, including impregnation of foams with ultrasonically generated aerosols of dissolved metal chlorides. By using appropriate multi-criteria analysis methods, the authors concluded that the novel process for the synthesis of Ni-based catalysts was superior in terms of economic and technological aspects. The aim of this research was to compare the novel synthesis processes for a Ni-Pd/Al2O3 catalyst and for other Ni-based catalysts by performing life cycle assessment and evaluating the environmental impacts of each synthesis process. Characterisation results
showed that the dominant environmental impact results from production of palladium (II) chloride for the Ni-Pd/Al2O3 catalyst synthesis process, while the other catalyst synthesis process had large environmental impacts associated with high energy consumption. The final outcome, obtained from comparison of normalisation results, indicates that the novel Ni-Pd/Al2O3 catalyst synthesis process had the smallest environmental impact.

AB  - The aim of this study was comparative analysis of catalysts with 5 and 20 wt.% Ni loading, with and without Pd additive, and it included: determination of reduction degrees, investigation on microstructure by scanning electron microscopy and chemical analysis by energy-dispersive spectroscopy. Ni/Al2O3 and Ni-Pd/Al2O3 catalysts supported on alpha-Al2O3-based foams were synthesized by aerosol assisted impregnation. Impregnation of the foams by ultrasonically aerosolized chlorides was followed by drying at 473 K and hydrogen reduction at 533 and 633 K. Lower Ni loading resulted in higher reduction degrees. Ni loading of 20 wt.% enabled relatively uniform coverage of the foam with a metallic coating. Nearly complete reduction was achieved at both temperatures with activity modifier (Pd). Reduction degrees reached 99.4 and 98.2 wt.% at 533 K for 5 and 20 wt.% of Ni, respectively.

AB  - Catalysts based on the Ni/Al2O3 system are used in a variety of catalytic processes. Catalysts are commonly synthesized through thermochemical routes (impregnation, precipitation, coprecipitation and others). The authors prepared a Ni-Pd/Al2O3 catalyst supported by a ceramic foam, using a novel method, whereby the foam was impregnated with aerosol. This paper evaluates the synthesis methods for the experimentally obtained Ni-Pd/Al2O3 catalyst in comparison with other Ni-based catalysts, using three multi-criteria analysis methods (SAW, TOPSIS and PROMETHEE II). The synthesis methods for Ni-based catalysts were compared with respect to the following parameters: preparation method, addition of the precipitation agent during preparation, forming and mixing precursors, filtration, drying procedure, calcination, reduction, and the presence of NiAl2O4. The final results indicate that the synthesis method for the Ni-Pd/Al2O3 catalyst is the best ranked in comparison with the others.

Avrami I equation was selected as the most favorable kinetic model and
used to determine activation energy of the NiO and NiCl2 reduction for the investigated temperature range (623–923 K) and time intervals (1–5 minutes).Theinvestigation enabled reaching conclusions about the reaction ability and rate of the reduction processes.

Properties of the samples before and after low-temperature hydrogen reduction (633K) were compared.Obtained results indicated that the synthesis ofNi/Al2O3 catalysts can be more efficient if chloride precursor for Ni is directly reduced by hydrogen during the synthesis process, without the calcination step. In addition, Ni-Pd/Al2O3 catalysts with different metal content were prepared by using chloride precursors. Lower reduction temperature was utilized and the chlorides were almost completely reduced at 533 K.

AB  - Technological evolution and growing demand for various high-tech devices have increased need for metals, both in terms of their diversity and quantities, resulting in more intense use of natural resources and generation of huge amounts of various waste materials. In contrast to base metals, advances in material science have given rise to a new group of metals, which are used in small or trace amounts to alter drastically the properties of matter. Whether in composite materials, like semiconductors or minor elements in alloys, these trace metals shape modern-day technology and, hence, are termed as Technology Metals (TM). Metals such as Sb, Co, Ga, Ge, In, Ta, the Platinum Group Metals (PGMs) and the Rare Earth Elements (REEs) are among the TM in which Europe is 100% import dependent. Development of the novel processing technologies will aim not only in securing raw material supply, but will rather aim to establish sustainable metallurgical processing, meaning establishing technologies for de-complexing the advanced material products with the minimum environmental footprint. Hydro and electro metallurgical steps make essential base with synergy to primary production route, advanced mechanical and minor pyro pretreatment step. However, absence of such extraction technologies, successfully applied on industrial scale, is still notable. To secure a reliable and sustainable supply of critical materials, innovative solutions need to be developed along the entire value chain. This transition requires multi-stakeholder partnerships that foster innovation and entrepreneurship, which can be obtained by applying the Triple Helix concept. Presented compilation of scientific, theoretical and experimental results, promotes an innovative synergy of various metals and industrial activities in metallurgy, resulting in profitable transformation of by-products and waste materials into resources. Focusing on treatment of specific by-products from zinc and copper primary production, as well on specific waste streams like WEEE and waste automotive catalysts, group is actively contribute to the EU sustainability policies.
