AB  - Low-cost and easily available natural zeolite is a promising adsorbent for metal ions removal in wastewater treatment. The possibility of using zeolitic tuff from Serbia in the form of Na-enriched natural zeolite (Na-Z) for the adsorption of Pb2+, Zn2+, Cu2+, and Ni2+ ions from wastewater was investigated in the presented paper. The research included Na-Z characterization and determination of adsorption kinetics in individual ion adsorption tests using Weber-Morris intraparticle diffusion model, non-linear pseudo-first-order (PFO), pseudo-second-order (PSO) and mixed-order (MO) kinetic models. The results indicate that the adsorption processes of metal ions on Na-Z are complex processes dominated by multiple rate-limiting mechanisms and best defined by the MO model. The mechanisms of ion diffusion and adsorption to active sites are equally represented in the Pb2+ adsorption process. The mechanism of ion adsorption on the active sites is the rate-limiting step in the Zn2+ adsorption process, while in the case of the Cu2+ and Ni2+ adsorption ion diffusion is the rate-limiting kinetic mechanism. Within the MO model, the PFO rate (external/internal diffusion) and the PSO rate (adsorption on active sites) were calculated and results were applied to a multicomponent wastewater sample in order to determine and explain the adsorption efficiency in wastewater treatment. The results show that the rate of adsorption of individual metal ions and the efficiency of ion removal from a multicomponent wastewater sample are influenced by several factors including the radius of the hydrated ion and the free energy of hydration. The achieved removal of metal ions by Na-Z is Pb2+ (89%) > Cu2+ (72%) > Zn2+ (61%) > Ni2+ (58%) and defines Na-enriched natural zeolite as an effective adsorbent in wastewater treatment.

AB  - More than 90 % of lead produced in Europe comes from secondary lead flows, of
which 85 % is attributed to waste lead-acid batteries (LAB). The main technological
approach for LAB processing implies pyrometallurgy by which 100–400 kg of waste slag
(WS) is generated per 1 ton of produced metallic lead. Due to recycling process parameters,
generated WS has great potential for releasing toxic elements contributing to environmental
pollution [1]. Namely, the most common flux in the recycling process is sodium-based
(Na2CO3) when alkali lead waste slag (ALWS) is generated, characterized as hazardous due
to its physical-chemical characteristics: high leachability, hygroscopic and pulverized
nature and, ultimately, instability [2,3]. Therefore, ALWS treatment prior to disposal should
be considered an integral part of waste LAB treatment systems. Immobilization of toxic
elements contained in slag is crucial and can be achieved by stabilization/solidification
processes (S/S) as one of the most widely used technologies in the treatment of heavy metal containing wastes for final disposal or utilization.
In this research, ALWS generated in the waste LAB recycling is used to determine
the S/S process efficiency as a function of the added binder amount (cement, in the range of
5 – 10 %), pre-treatment (the removal of water-soluble compounds), and activator addition
(MgO). The liquid to solid (L/S) ratio was 1/4 in all S/S experiments. The basic parameters
for the effectiveness assessments were compressive strength (UCS) and pollutants leaching
(Method 1311 Toxicity characteristic leaching procedure, TCLP).
The conclusion is that, contrary to the pre-treatment process, the addition of MgO has
an overall positive effect on the S/S process of ALSW, ensuring both mechanical and
chemical stability. This ALWS solidificate, obtained through the S/S process by using MgO
as an activator, is safe for disposal, according to environmental regulations.

AB  - Natural zeolite is a good sorbent for many cations due to its specific porous structure. The degree of sorption efficiency depends on the cation type and the availability of exchange positions in the zeolite lattice. The aim of this work is to
examine the synthesis possibility of a new adsorbent based on natural zeolite and hydroxyapatite. The adsorbent was prepared mechanochemically by using clinoptilolite-rich zeolite tuff from the Slanci deposit (Serbia) and hydroxyapatite
obtained by the hydrothermal process. The milling process was performed in a ball mill and optimized regarding contact time and milling speed. For the synthesis of zeolite/hydroxyapatite adsorbent (ZHAp), optimal values for these two parameters were 10 min and 250 rpm, respectively. The resulting sample ZHAp was characterized by X-ray powder diffraction, thermal analysis and scanning electron microscopy. Diffraction analysis of the ZHAp confirmed the presence of the most abundant mineral in zeolite tuff - clinoptilolite and hydroxyapatite. Needle-like crystals of hydroxyapatite on the clinoptilolite surface are observed in SEM images. Zeolite/hydroxyapatite sample is thermally stable at 800 °C. Adsorption properties of ZHAp were examined for nickel and chromium ions, towards which natural zeolite shows a low affinity. The presence of hydroxyapatite on the zeolite surface led to an increase in the adsorption capacity more than two times for both tested ions compared to the initial zeolite tuff.

AB  - More than 90% of lead produced in Europe comes from secondary lead flows, of which 85% is attributed to waste lead-acid batteries (LAB). The main technological approach for LAB processing implies pyrometallurgy by which 100–400 kg of waste slag (WS) is generated per 1 ton of produced metallic lead. Due to recycling process parameters, generated WS has great potential for releasing toxic elements contributing to environmental pollution [1]. Namely, the most common flux in the recycling process is sodium-based (Na2CO3) when alkali lead waste slag (ALWS) is generated, characterized as hazardous due to its physical-chemical characteristics: high leachability, hygroscopic and pulverized nature and, ultimately, instability [2,3]. Therefore, ALWS treatment prior to disposal should be considered an integral part of waste LAB treatment systems. Immobilization of toxic elements contained in slag is crucial and can be achieved by stabilization/solidification processes (S/S) as one of the most widely used technologies in the treatment of heavy metal-containing wastes for final disposal or utilization.
In this research, ALWS generated in the waste LAB recycling is used to determine the S/S process efficiency as a function of the added binder amount (cement, in the range of 5 – 10 %), pre-treatment (the removal of water-soluble compounds), and activator addition (MgO). The liquid to solid (L/S) ratio was 1/4 in all S/S experiments. The basic parameters for the effectiveness assessments were compressive strength (UCS) and pollutants leaching (Method 1311 Toxicity characteristic leaching procedure, TCLP).
ALWS containing 3.5 Pb, 15.5 Na, 14.0 S, and 24.7 Fe was mixed with cement and water. The results of UCS showed that all produced solidificates exceeded the required value of 0.35 MPa [4], yet the mixture containing 7.5 % of the cement has the best mechanical properties (2.1 MPa). This sample was further analyzed and the TCLP results showed that the Pb concentration exceeds the limit values for stabilized slag (10.4 and 5 ppm, respectively). In the next set, ALWS was pre-treated by continuous rinser (30 ºC, 60 min, L/S 4). Obtained results of UCS (0.4 MPa) and TCLP (53.4 ppm) were unfavorable. The last set, besides the binder, included activator addition (MgO, 7.5 %) altogether with a high content of untreated ALWS (85 %). Analysis of the produced solidificates showed favorable and acceptable results (USC - 3.3 MPa, TCLP – Pb 4.5 ppm). 
Generally, in an alkaline slag-leaching solution lead precipitates as a complex mixture (PbO, Pb(OH)2, PbO×Pb(OH)2). Lead oxides are amphoteric and dissolve in an alkaline aqueous solution, leading to poor solidification. Also, lead present in surface coatings around cement grains prevents cement hydration. Simultaneously, the migration of lead to the surrounding water is promoted. The negative effect of the pre-treatment is a consequence of the sulfate ions absence, as well as the absence of the ettringite (Ca6Al2(SO4)3(OH)12×26H2O) and sulfate- AFm phases [5], which negatively affect the strength of the product. The addition of MgO benefits the S/S process through hydrotalcite-like phase formation ([M1-

abstract = "More than 90% of lead produced in Europe comes from secondary lead flows, of which 85% is attributed to waste lead-acid batteries (LAB). The main technological approach for LAB processing implies pyrometallurgy by which 100–400 kg of waste slag (WS) is generated per 1 ton of produced metallic lead. Due to recycling process parameters, generated WS has great potential for releasing toxic elements contributing to environmental pollution [1]. Namely, the most common flux in the recycling process is sodium-based (Na2CO3) when alkali lead waste slag (ALWS) is generated, characterized as hazardous due to its physical-chemical characteristics: high leachability, hygroscopic and pulverized nature and, ultimately, instability [2,3]. Therefore, ALWS treatment prior to disposal should be considered an integral part of waste LAB treatment systems. Immobilization of toxic elements contained in slag is crucial and can be achieved by stabilization/solidification processes (S/S) as one of the most widely used technologies in the treatment of heavy metal-containing wastes for final disposal or utilization.
In this research, ALWS generated in the waste LAB recycling is used to determine the S/S process efficiency as a function of the added binder amount (cement, in the range of 5 – 10 %), pre-treatment (the removal of water-soluble compounds), and activator addition (MgO). The liquid to solid (L/S) ratio was 1/4 in all S/S experiments. The basic parameters for the effectiveness assessments were compressive strength (UCS) and pollutants leaching (Method 1311 Toxicity characteristic leaching procedure, TCLP).
ALWS containing 3.5 Pb, 15.5 Na, 14.0 S, and 24.7 Fe was mixed with cement and water. The results of UCS showed that all produced solidificates exceeded the required value of 0.35 MPa [4], yet the mixture containing 7.5 % of the cement has the best mechanical properties (2.1 MPa). This sample was further analyzed and the TCLP results showed that the Pb concentration exceeds the limit values for stabilized slag (10.4 and 5 ppm, respectively). In the next set, ALWS was pre-treated by continuous rinser (30 ºC, 60 min, L/S 4). Obtained results of UCS (0.4 MPa) and TCLP (53.4 ppm) were unfavorable. The last set, besides the binder, included activator addition (MgO, 7.5 %) altogether with a high content of untreated ALWS (85 %). Analysis of the produced solidificates showed favorable and acceptable results (USC - 3.3 MPa, TCLP – Pb 4.5 ppm). 
Generally, in an alkaline slag-leaching solution lead precipitates as a complex mixture (PbO, Pb(OH)2, PbO×Pb(OH)2). Lead oxides are amphoteric and dissolve in an alkaline aqueous solution, leading to poor solidification. Also, lead present in surface coatings around cement grains prevents cement hydration. Simultaneously, the migration of lead to the surrounding water is promoted. The negative effect of the pre-treatment is a consequence of the sulfate ions absence, as well as the absence of the ettringite (Ca6Al2(SO4)3(OH)12×26H2O) and sulfate- AFm phases [5], which negatively affect the strength of the product. The addition of MgO benefits the S/S process through hydrotalcite-like phase formation ([M1-
2+M 3+(OH) ][A   n-×mH O], M2+=Mg, Zn, Ni, Fe; M3+=Al, Cr, Fe; A=CO 2-,
NO -, Cl-), a compound capable of metal adsorption, hence immobilization [6].
The conclusion is that, contrary to the pre-treatment process, the addition of MgO has an overall positive effect on the S/S process of ALSW, ensuring both mechanical and chemical stability. This ALWS solidificate, obtained through the S/S process by using MgO as an activator, is safe for disposal, according to environmental regulations.",

AB  - The aim of this study was to investigate a possibility of synthesis of porous ceramics with controlled open porosity, which could be used as sorbents and catalyst supports. Two organic additives were used to obtain open porosity: polystyrene beads and cellulose fibers, which are mixed with kaolin clay powder and the appropriate water content. Samples were sintered at 1050 oC for 1 h. Characterization of the obtained products included X-ray powder diffraction analysis (XRPD), Fourier-transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), thermogravimetric analysis (TGA) and elemental CHNS analysis. In addition, porosity was examined by quantification of visual information. The specific surface areas were determined by the Brunauer–Emmett–Teller (BET) method. Also, density and compressive strength of the obtained samples were assessed. It was determined that by sintering, the organic component completely leaves the system. For samples prepared with polystyrene beads and with cellulose fibers, satisfactory mechanical properties were obtained: compressive strengths were 1.42 and 1.56 MPa, respectively. It was noted that significantly higher open porosity was obtained by using polystyrene beads as a sacrificial template (porosity of ̴56 %) instead of cellulose fibers (porosity of ̴6 %).

AB  - In order to reflect possible issues in future sole e-waste processing, an electrolyte of complex chemical composition reflecting system of sole e-waste processing was obtained by following a specially designed pyro-electrometallurgical method. The obtained non-standard electrolyte was further used for the purpose of comprehensive metal interference evaluation on the copper solvent extraction (SX) process. Optimization of the process included a variation of several process parameters, allowing determination of the effect of the most abundant and potentially the most influential impurities (Ni, Sn, Fe, and Zn) and 14 other trace elements. Moreover, comparing three commercial extractants of different active chelating groups, it was determined that branched aldoxime reagent is favorable for Cu extraction from the chemically complex system, as can be expected in future e-waste recycling. The results of this study showed that, under optimal conditions of 20 vol.% extractant concentration, feed pH 1.5, O/A ratio 3, and 10-min phase contact time, 88.1% of one stage Cu extraction was achieved. Co-extraction of the Fe, Zn, Ni, and Sn was under 8%, while Pb and trace elements were negligible. Optimal conditions (H2SO4 180 g/L, O/A = 2, and contact time 5 min) enabled 95.3% Cu stripping and under 6% of the most influential impurities. In addition, an impurity monitoring and distribution methodology enabled a better understanding and design of the process for the more efficient valorization of metals from e-waste.

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 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.

abstract = "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

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.

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  - This paper describes the synthesis of tungsten disulfide (WS 2 ) powder by the sulfurization of tungsten trioxide (WO 3 ) particles in the presence of additive potassium carbonate (K 2 CO 3 ) in nitrogen (N 2 ) atmosphere, first at lower temperature (200 ◦ C) and followed by reduction at higher temperature (900 ◦ C). In addition, the ultrasonic spray pyrolysis of ammonium meta-tungstate hydrate (AMT) was used for the production of WO 3 particles at 650 ◦ C in air. The HSC Chemistry® software package 9.0 was used for the analysis of chemistry and thermodynamic parameters of the processes for WS 2 powder synthesis. The crystalline structure and phase composition of all synthesized powders were analyzed by X-ray diffraction (XRD) measurements. The morphology and chemical composition of these samples were examined by scanning electron microscopy (SEM) combined with energy dispersive X-ray analysis (EDX).

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.

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.
