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 wereapplied 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  naturalzeolite  as  an  effective  adsorbent  in  wastewater treatment.

AB  - Acid mine drainage is a challenging environmental problem caused by mining activities.
Long-term copper ore exploitation and vast amounts of mining waste lead to severe soil
contamination as well as river and groundwater pollution. In this paper, research is focused
on utilizing waste mine waters and off-balance parts of the mine deposit (such as flotation
tailings) and converting their negative characteristics to an environmentally friendly one. In
the authors’ previous work, acid mine water from Robule, which is part of the Bor copper
mining and smelting complex in Serbia, was successfully treated using flotation tailings, and
the resulting solution was suitable for safe discharge. This paper investigates the characteristics
of the solid residue that remained after the treatment of the modified flotation tailings in order
to evaluate the possibility of its safe disposal back into the environment. The solid residue
was subjected to TCLP and EN 12457-4 tests as standard procedures that assess the leaching
characteristics of a material. The solid residue was also exposed to long-term leaching with
melted snow to simulate environmental conditions for one year. This drainage water was
analyzed and compared with the results of the standard leaching procedures. The investigated
treatments lead to improved economic and environmental effects, while the process itself is
adjusted to preserve the environment.

AB  - Acid mine drainage (AMD) is a waste from mining sites, usually acidic, with high concentrations of sulfates and heavy metal ions. This study investigates the AMD neutralization process using fly ash (FA) as an alternative material. Samples of FA from coal-fired power plants in Serbia (“Nikola Tesla” (EF) and “Kostolac” (KOST)) were analyzed and used. The results were compared with the treatment efficiency of commercial neutralization agent (NaOH). The alkaline nature of FA was the basis for use in the treatment process of the extremely acid Lake Robule (pH 2.46), located in the mining areas of eastern Serbia. The optimal S/L ratio for the AMD neutralization process determined for EF was 25 wt.%, and for KOST it was 20 wt.%. The mechanism of the neutralization process was analyzed using the ANC test and PHREEQC program. The element concentrations and pH values in solutions indicated that FA samples could neutralize Lake Robule with more than 99% of Al, Fe, Cu, Zn, and more than 89% of Pb precipitated. Formation of insoluble (oxy)hydroxide forms (Fe3+ and Al3+ ions) creates favorable conditions for co-precipitation of other trace metals (Cu, Zn, Ni, Pb, and Cd) from AMD, which is further enhanced by cation adsorption on FA particles. FA proved to be a more effective neutralization agent than NaOH due to its adsorption effect, while among the FA samples, KOST was more effective due to the aging process through the carbonization reaction. Using FA as an alternative material is a promising and sustainable method for treating AMD, with economic and environmental benefits.

AB  - Fly and bottom ash(es) are the most abundant generated by-products of coal combustion in thermal power plants. This investigation offers a sustainable solution of a double and circular use of industrial waste material in civil engineering practices; i.e., fly ash (FA) as an eco-efficiently, low-cost material for As(V) adsorption, as well as an additive in building materials. A goethite impregnated sample (FAG) was synthesized and optimized using the column precipitation procedure, then thoroughly, structurally and morphologically characterized using liquid nitrogen porosimetry (BET), X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM) and Mossbauer spectroscopy (MS) techniques. The data from the equilibrium adsorption were fitted by linear and non-linear isotherm models; the optimal capacity of FAG/As(V) removal was calculated from the Langmuir model at 31.742 mg g(-1) for 45 degrees C. The kinetics of adsorption process has shown the pseudo-second-order kinetic model (PSO). The Weber-Morris model was applied to determine the intra-particle diffusion as a limiting step of reaction. The low pH dependant FAG leaching confirmed the efficient use of non-hazardous waste material in arsenic removal; furthermore, it also validated the new added value of the used/spent adsorbent as an adhesive in building materials possessing advanced mechanical properties.

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.

AB  - High flexibility of hydrometallurgical operations as well as economic and environmental acceptability, offer the opportunity to selectively obtain metals in the early stages of the processing. This enables the application of hydrometallurgical operations in processing of ores which, due to their complex composition or low copper content, are not suitable for pyrometallurgical treatment. In contrast to sulfide minerals, leaching of oxide ores does not requires presence of oxidizing agent. This paper presents the results of influence of temperature on the leaching degree of copper from pyritechalcopyrite concentrate by sulfuric acid solution at atmospheric pressure. According to the obtained results, it was found that an increase in the leaching temperature significantly contributes to the increase in the leaching efficiency, where after 6 hours of leaching at 40°C achieved efficiency was 90.6%.

AB  - Flotation tailings rich in carbonate minerals from the tailings deposit of the copper mine Majdanpek (Serbia) were applied for neutralization of the water taken from the extremely acidic Lake Robule (Bor, Serbia). Tests conducted in Erlenmeyer flasks showed that after neutralization of the lake water to pH 7, over 99% of aluminum (Al), iron (Fe), and copper (Cu) precipitated, as well as 92% of Zn and 98% of Pb. In order to remove residual Mn and Ag, the water was further treated with NaOH. After treatment with NaOH, all concentrations of the metals in the lake water samples were below discharge limits for municipal wastewater according to the national legislation of the Republic of Serbia. The results of this work suggest that mining waste could be used for active neutralization of the acid mine drainage. The use of the mining waste instead of lime could reduce the costs of the active treatment of the acid mine drainage.

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  - 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  - Since commissioning in 1961, the copper mine Majdanpek, a part of the Mining and Smelting Complex Bor (RTB Bor), produced approximately 378 million tons of flotation tailings. Semiquantitative mineralogical analysis of the flotation tailings revealed significant content of carbonate minerals (approximately 20-25 %), indicating high acid neutralization capacity. Also, approximately 70 % of copper is in the form of the oxide mineral cuprite (Cu2O). Copper can be easily leached from cuprite by using sulphuric acid. The RTB Bor copper smelter generates 8.7 m(3)h(-1) of extremely acidic waste effluent (142.4 kgm(-3) of sulphuric acid, pH - 0.464) with relatively high concentrations of dissolved metals and metalloids (Cu, Fe, Zn, Pb and As). The effluent is currently treated with hydrated lime. The present study focused on application of flotation tailings as a neutralizing agent for acidic effluents. Laboratory experiments followed by computer simulation of the industrial process showed that 99% of the acid can be neutralized with flotation tailings in a series of six reactors resulting in the final copper concentration of 1.55 gL(-1). Benefits of the proposed process are: lower environmental impact of the process and reduced costs of neutralization of the acidic effluent from the copper smelter.

abstract = "Since commissioning in 1961, the copper mine Majdanpek, a part of the Mining and Smelting Complex Bor (RTB Bor), produced approximately 378 million tons of flotation tailings. Semiquantitative mineralogical analysis of the flotation tailings revealed significant content of carbonate minerals (approximately 20-25 %), indicating high acid neutralization capacity. Also, approximately 70 % of copper is in the form of the oxide mineral cuprite (Cu2O). Copper can be easily leached from cuprite by using sulphuric acid. The RTB Bor copper smelter generates 8.7 m(3)h(-1) of extremely acidic waste effluent (142.4 kgm(-3) of sulphuric acid, pH - 0.464) with relatively high concentrations of dissolved metals and metalloids (Cu, Fe, Zn, Pb and As). The effluent is currently treated with hydrated lime. The present study focused on application of flotation tailings as a neutralizing agent for acidic effluents. Laboratory experiments followed by computer simulation of the industrial process showed that 99% of the acid can be neutralized with flotation tailings in a series of six reactors resulting in the final copper concentration of 1.55 gL(-1). Benefits of the proposed process are: lower environmental impact of the process and reduced costs of neutralization of the acidic effluent from the copper smelter.",

AB  - Stabilization and solidification process is considered to be the best available technique for the treatment of industrial waste sludge and solid waste. This PhD thesis presents investigations of development and optimization of the S/S process of waste sludge generated during the wastewater treatment in primary copper smelter, as well as the stabilization process of clinker formed during the treatment of waste sludges with copper content from hydrometallurgical zinc processing which are characterized by a high content of base and toxic metals (Cu, Zn, Pb, Ni i As). The optimization of the S/S process of wastewater treatment sludge from primary copper smelter is done by varying the ratio sludge/binder and the composition of the binder (the agent for stabilization). Fly ash (FA), individually or in mixtures with hydrated lime (HL) and composite Portland cement (PC), was investigated as the stabilization agent. The efficiency of the S/S process is determined by measuring the unconfined compressive strength (UCS) and leaching stability of solidificates by using two standard leaching tests: TCLP and EN 12457-4. The two leaching tests gave different classification of the same treated waste as hazardous or non-hazardous. For that reason the setting of a long-term leaching test under the real environmental conditions is proposed and applied within the PhD thesis. The test includes exposure of solidificates to the effect of atmospheric water during one year and collection of drainage water during the summer and winter season in order to determine a more realistic assessment of the stability of the treated waste. It is determined that the leaching level of contaminants depends on the buffer capacity of the solidificates and it was analyzed by using the ANC test. Phases in the solidified structure that caused the differences in the UCS and leaching stability between the obtained solidificates were not detected in the mineralogical analysis done by the XRD method due to the generally amorphous structure of the solidified matrix. Differential ANC analysis (d-ANC) is an effective alternative in examining the solidified structure, and its results are paired with Eh-pH diagrams, which is a novelty in the application of this analysis presented in the PhD thesis. The application of the modified d-ANC analysis determined the presence of unreacted calcium(II)-hydroxide added in excess, which caused an increase of the buffer capacity and leaching stability of solidificates, but also a decrease of the UCS...

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  - The presented study investigates solidification/stabilization process of hazardous heavy metals/arsenic sludge, generated after the treatment of the wastewater from a primary copper smelter. Fly ash and fly ash with addition of hydrated lime and Portland composite cement were studied as potential binders. The effectiveness of the process was evaluated by unconfined compressive strength (UCS) testing, leaching tests (EN 12457-4 and TCLP) and acid neutralization capacity (ANC) test. It was found that introduction of cement into the systems increased the UCS, led to reduced leaching of Cu, Ni and Zn, but had a negative effect on the ANC. Gradual addition of lime resulted in decreased UCS, significant reduction of metals leaching and high ANC, due to the excess of lime that remained unreacted in pozzolanic reaction. Stabilization of more than 99% of heavy metals and 90% of arsenic has been achieved. All the samples had UCS above required value for safe disposal. In addition to standard leaching tests, solidificates were exposed to atmospheric conditions during one year in order to determine the actual leaching level of metals in real environment. It can be concluded that the EN 12457-4 test is more similar to the real environmental conditions, while the TCLP test highly exaggerates the leaching of metals. The paper also presents results of differential acid neutralization (d-AN) analysis compared with mineralogical study done by scanning electron microscopy and X-ray diffraction analysis. The d-AN coupled with Eh-pH (Pourbaix) diagrams were proven to be a new effective method for analysis of amorphous solidified structure.

The aim of the study was to investigate leaching mechanism and behaviour of lead and arsenic from sodium lead slag previously stabilized/solidified in concrete using additives: MgO, CaO, Ba(OH)(2) and gypsum. The influence of selected additives on pollutant release was also investigated. The results of the NEN 7375 leaching test indicate dissolution of lead and arsenic from the outer layer of specimens, followed by depletion of possible mobile forms. Analysis of leachates from samples with various compositions showed that proper selection of additives may reduce leaching of Pb and As below the specified limits.

AB  - The previous inadequate treatment of off-gas in RTB Bor in Serbia has resulted in serious pollution of the environment and the possibly high losses of copper through the effluent flows. The project of New Copper Smelter RTB Bor, besides the new flash smelting furnace (FSF) and the reconstruction of Pierce-Smith converter (PSC), includes more effective effluent treatment. Paper presents an analysis of the new FSF and PSC off-gas treatment, determination of copper losses throughout generated wastewaters and discussion of its possible valorization. Assumptions about the solubility of metals phases present in the FSF and PSC off-gas, obtained by the treatment process simulation, were compared with the leaching results of flue dusts. Determined wastewaters characteristics indicate that the PSC flow is significantly richer in copper, mostly present in insoluble metallic/sulfide form, while the FSF flow has low concentration of copper in the form of completely soluble oxide/sulfate. The possible scenario for the copper valorization, considering arsenic and lead as limiting factors, is the separation of the FSF and PSC flows, return of the metallic/sulfide solid phase to the smelting process and recovery from the sulfate/oxide liquid phase.

AB  - Wastewater treatment sludge from a primary copper smelter is characterized as hazardous waste that requires treatment prior to disposal due to its significant contents of heavy metals and arsenic. The aim of the presented study was to investigate the feasibility and the effectiveness of a solidification/stabilization process of the sludge using fly ash and lime as binders. The effectiveness of the process was evaluated by Unconfined Compressive Strength (UCS) testing, leaching tests (EN 12457-4 and Toxicity Characteristic Leaching Procedure (TCLP)) and Acid Neutralization Capacity (ANC) tests. All the samples reached the target UCS value of 0.35 MPa. The calcium to silicon concentration ratio (cCa/cSi), determined by X-ray fluorescence analysis, was identified as main factor governing strength development. Inductively coupled plasma-optical emission spectrometry analyses of solutions after leaching tests showed excellent stabilization of Cu, Ni, Pb and Zn (above 99 %) and arsenic (above 90 %) in samples with high Ca(OH)2 content. Results of the ANC test indicated that the buffering capacity of solidified material linearly depended on Ca concentration in FA and lime. Samples with 20 % of binder having 50 % of FA and 50 % of lime met all the requirements for safe disposal.
AB  - Mulj koji nastaje tretmanom otpadne vode iz primarne topinice bakra predstavlja opasan otpad koji se mora tretirati pre odlaganja usled visokog sadržaja teških metala i arsena. Cilj prezentovanog rada je ispitivanje izvodljivosti i efikasnosti procesa solidifikacije/stabilizacije ovog mulja korišćenjem letećeg pepela i hidratisanog kreča kao agensa za stabilizaciju. Efikasnost procesa se određivala merenjem pritisne čvrstoće (UCS) solidifikata, testovima luženja (EN 12457-4 i Toxicity Characteristic Leaching Procedure (TCLP)) i testom kapaciteta za neutralizaciju kiseline (ANC test). Svi ispitivani uzorci su imali pritisnu čvrstoću iznad zahtevanih 0,35 MPa. Odnos koncentracija kalcijuma i silicijuma (cCa/cSi) u uzorcima, određen rendgensko-fluorescentnom analizom, je identifikovan kao glavni faktor razvoja pritisne čvrstoće. Optička emisiona spektrometrijska analiza sa indukovano spregnutom plazmom rastvora nakon testova luženja je pokazala odličnu stabilizaciju Cu, Ni, Pb i Zn (iznad 99 %) i arsena (iznad 90 %) u uzorcima sa visokim sadržajem Ca(OH)2. Rezultati ANC testa ukazuju na to da puferski kapacitet solidifikovanog materijala linearno zavisi od koncentracije Ca u letećem pepelu i kreču. Uzorak sa 20 % veziva sastava 50 % leteći pepeo i 50 % hidratisani kreč ispunjava sve zahtevane uslove da bude bezbedno odložen.

AB  - Used electronic equipment became one of the fastest growing waste streams in the world. In the past two decades recycling of printed circuit boards (PCBs) has been based on pyrometallurgy, highly polluting recycling technology which causes a variety of environmental problems. The most of the contemporary research activities on recovery of base and precious metals from waste PCBs are focused on hydrometallurgical techniques as more exact, predictable and easily controlled. In this paper mechanically pretreated PCBs are leached with nitric acid. Pouring density, percentage of magnetic fraction, particle size distribution, metal content and leach ability are determined using optical microscopy, atomic absorption spectrometry (AAS), X-ray fluorescent spectrometry (XRF) and volumetric analysis. Three hydrometallurgical process options for recycling of copper and precious metals from waste PCBs are proposed and optimized: the use of selective leachants for recovery of high purity metals (fluoroboric acid, ammonia-ammonium salt solution), conventional leachants (sulphuric acid, chloride, cyanide) and eco-friendly leachants (formic acid, potassium persulphate). Results presented in this paper showed that size reduction process should include cutting instead of hammer shredding for obtaining suitable shape & granulation and that for further testing usage of particle size -3 +0.1mm is recommended. Also, Fe magnetic phase content could be reduced before hydro treatment.
