AB  - Smelting used to be less efficient; therefore, wastes obtained from historical processing at smelter plants usually contain certain quantities of valuable metals. Upon the extraction of useful metal elements, metallurgical slag can be repurposed as an alternative mineral raw material in the building sector. A case study was conducted, which included an investigation of the physico-chemical, mineralogical, and microstructural properties of Pb–Zn slag found at the historic landfill near the Topilnica Veles smelter in North Macedonia. The slag was sampled using drill holes. The mineralogical and microstructural analysis revealed that Pb–Zn slag is a very complex and inhomogeneous alternative raw material with utilizable levels of metals, specifically Pb (2.3 wt.%), Zn (7.1 wt.%), and Ag (27.5 ppm). Crystalline mineral phases of wurtzite, sphalerite, galena, cerussite, akermanite, wüstite, monticellite, franklinite, and zincite were identified in the analyzed samples. The slag’s matrix consisted of alumino-silicates, amorphous silicates, and mixtures of spinel and silicates. Due to the economic potential of Pb, Zn, and Ag extraction, the first stage of reutilization will be to transform metal concentrates into their collective concentrate, from which the maximum amount of these crucial components can be extracted. This procedure will include combination of gravity concentration and separation techniques. The next step is to assess the Pb–Zn slag’s potential applications in civil engineering, based on its mineralogical and physico-mechanical properties. Alumino-silicates present in Pb–Zn slag, which contain high concentrations of SiO2, Al2O3, CaO, and Fe2O3, are suitable for use in cementitious building composites. The goal of this research is to suggest a solution by which to close the circle of slag’s reutilization in terms of zero waste principles. It is therefore critical to thoroughly investigate the material, the established methods and preparation processes, and the ways of concentrating useful components into commercial products.

AB  - This paper presents results of investigations of the possibility of using “Glavatske Kuće”-Kotor limestone (Montenegro) as filler in various industry branches. Micronization methods, granulometric composition, oil and water absorption and degree of whiteness were investigated, and chemical and thermal analyses (DT/TG) were performed. Physico-chemical properties of this limestone classify it among high quality carbonate raw materials with relatively high CaCO3 content of 97.68 %, as well as low MgCO3 content of 1.849 % and low silicate content (SiO2 0.24 %). Its quality satisfies requirements of standards on using of calcium carbonate as filler in industry of paints and coatings; glass industry; foundry industry; sugar industry and metallurgy. Due to the low degree of whiteness (77,85 %) “Glavatske Kuće” limestone cannot be used in pharmaceutical and cosmetics industry, paper industry. Because of increased MgO content, limestone “Glavatske kuće” cannot be used in the fertilizers industry. Due to relatively high content of heavy metals, Cu (47 ppm), Ni (50 ppm) and Cd (8 ppm), as well as biogenic elements P2O5 (0.0234 %), K2O (0,0157 %), “Glavatske Kuće” limestone cannot be used in production of cattle feed and for neutralization of acidic soils.

AB  - Biocomposite hydroxyapatite/poly(vinyl alcohol)/chitosan/gentamicincoatings were fabricated on titanium by an electrophoretic deposition process (EPD) from an aqueous suspension using  the  constant voltage  method. Characterization of  the  deposited coatings  was performed by scanning electron  micros-copy with field emission (FE–SEM), Fourier transform infrared spectroscopy (FT-IR), and X-ray diffrac-tion  (XRD)  after  immersion  in  simulated  body  fluid  (SBF)  at  37°C.  The  concentration  of  the  released gentamicin was determined using high-performance liquid chromatography (HPLC) coupled with a mass spectrometer (MS). The release profile confirmed an initial “burst-release effect”with ~ 30% of the gen-tamicin released in the first 48 h, which could be of assistance in the prevention of biofilm formation. An-tibacterial activity was proven by the agar diffusion method on Staphylococcus aureusTL and Escherich-ia coliATCC 25922 bacterial strains. Cytotoxicity was tested by the dye exclusion test (DET) on MRC-5 and L929 fibroblast cell lines, with both coatings expressing nontoxicity. The results showed the high ap-plicability potential of a poly(vinyl alcohol)-based biocomposite coating for medical purposes.

AB  - The glass was prepared by the standard melt-quenching technique. The crystallization of powder glass from the system Li2O-Al2O3-GeO2-P2O5 was studied. The investigations were performed under non-isothermal and isothermal conditions using the AAS, DTA, XRD and FTIR methods. The aim of this research was to study the ease of glass formation, crystallization and crystal structure of obtained phases. The results showed that the glass crystallizes by primary crystallization. LiGe2(PO4)3 was formed as the primary phase, until detectable traces of GeO2 were formed as secondary. The influence of particle size of the glass powder samples in the range 0-1 mm on the temperature of the DTA crystallization peak, Tp, the peak height (T)p and the parameter Tp2/(T)p was studied. It was demonstrated that for the particle size in the range of 0.05-0.35 mm surface and volume crystallization were significant, while the particle size >0.35 mm according to the volume crystallization was dominant.

AB  - Microplastics (MPs), the long-lasting anthropogenic contaminant omnipresent in the environment, have become a threat to ecosystems’ function and living organisms’ health, potentially harming the food chain globally. The presence of MPs emerged on a worldwide scale, while the evidence of microplastic particles is already being detected in human tissues. Terrestrial environments are sinks for plastic deposition and are one of the main routes of MPs reaching the groundwater and water bodies. In this regard, urban soils could significantly contribute to overall plastic pollution even though it have been mostly neglected by the research investigations carried out so far. Herein, we investigated MPs abundance in the soils of Belgrade, a city located in the northeast of Serbia, the capital and the most populated city in Serbia. Two sampling points chosen to represent the pollution gradient were the city center zone, close to the highway (BG1), and Košutnjak, the urban forest area around 7 km distant from the center (BG2). MPs extraction was performed using a density separation method, by saturated NaCl solution (1.2 g cm-3). Before extraction, soil organic matter was digested by 30% H2O2. Found average concentration of MPs was 400 items per kg of dry soil sampled in BG1. Soil from Košutnjak contained no MPs according to our findings. MPs abundance found in sampled soils from Belgrade is in agreement with previous reports analyzing urban areas. Isolated plastic particles were identified and counted using a polarizing microscope (Carl Zeiss Jena Pol-U). All found items were white/transparent fragments, characterized afterward by ATR-FTIR spectroscopy using a Thermo Scientific Nicolet iS50 spectrophotometer. Detected polymer types were polystyrene (PS) and phosphorylated cardanol prepolymer (PCP), suggesting the insulation, packing, and rubber materials as potential pollution sources. Transportation, overload of customer goods and packaging, construction, and building activities are the prevailing anthropogenic origins of MPs accumulation in urban environments. Further investigations will aim to reveal the relations between MPs and other pollutants and the potential impact on soil biota.

MPs abundance found in sampled soils from Belgrade is in agreement with previous reports analyzing urban areas. Isolated plastic particles were identified and counted using a polarizing microscope (Carl Zeiss Jena Pol-U). All found items were white/transparent fragments, characterized afterward by ATR-FTIR spectroscopy using a Thermo Scientific Nicolet iS50 spectrophotometer. Detected polymer types were polystyrene (PS) and phosphorylated cardanol prepolymer (PCP), suggesting the insulation, packing, and rubber materials as potential pollution sources. Transportation, overload of customer goods and packaging, construction, and building activities are the prevailing anthropogenic origins of MPs accumulation in urban environments. Further investigations will aim to reveal the relations between MPs and other pollutants and the potential impact on soil biota.",

AB  - Zeolites are a group of natural and synthetic inorganic compounds. They have specific physicochemical properties suitable for industrial application [1,2]. According to their origin, variety of chemical composition, structural characteristics and application, zeolites form a specific group of minerals within the tectosilicates. In sedimentary formations rich in zeolites, the most characteristic minerals that are present are: clinoptilolite/hailandite, chabazite, mordenite, erionite, phillipsite and analcime. The most widespread zeolite of sedimentary origin is represented by the HEU series (clinoptilolite-heylandite). Its general crystal chemical formula is (Na,K,Ca)6Al6Si30O72nH2O.. Based on chemical and X-ray powder diffraction analysis, it is not possible to separate clinoptilolite and hoylandite . This is due to their isostructural nature. To identify these two isostructural minerals, even today, the simplest so-called Mampton's test [3]. Mumpton [4]. The results of X-ray diffraction analysis of thermally treated clinoptilolitic tuffs from the Zlatokop and Beočin deposits will be presented in this paper. The interplane distance values will be shown in the characteristic temperature range from 400oC to 500oC (when the first polymorphic transition occurs). These values characterize the zeolitic tuffs of our deposits in a certain way.

AB  - Microfibers, as a considerable component of microplastic pollution in the environment have received
notable attention during past years. Fast fashion and extensive use of synthetic and semi-synthetic outfits,
aging, and discharge of used textile items are dominant sources of microfiber generation and ending up in
urban soils. Herein, we examined microfibers' presence in the urban soils of Sremska Mitrovica and Bor.
A flotation method based on density separation using saturated NaCl solution was utilized to assess
microplastics concentration in soils. The abundance of microfibers was 200 and 600 items per kg of soil,
respectively. Fiber structure was confirmed by ATR-FTIR analysis. Items isolated from soil from Sremska
Mitrovica contained the natural fiber of cotton, while microfibers detected in soil from Bor referred to
semi-synthetic polymer, viscose, i.e. rayon. Despite similar chemical structures based on cellulose,
differences in IR spectra allowed the distinguishing of these fiber types. This paper provides insight into
the current state of environmental pollution by microplastic fibers and suggests potential origin. More indepth
research on fiber content in soils, measures of prevention, and subsequent remediation should be
carried out to face the challenge of microfibers presence in the ecosystem, their entering the food chain,
and their impact on biota.

AB  - This paper presents the effect of K2O content on phase composition of the nanocrystallized niobium germanate glasses. It was shown that the exothermal peak temperature, Tp, shifted toward the higher temperatures with increasing content of K2O. Such increase of K2O content causes a decrease of GeO2 content in the primary phases. The crystals below 100 nm were detected in the samples.

AB  - Phyllosilicate mineral pyrophyllite is predominantly used in the ceramic industry because it exhibits high refractoriness. Due to its thermal transformation into mullite, pyrophyllite is stable at elevated temperatures, making it a suitable mineral additive for refractory non-shaped materials and various ceramic shaped products. In this study, pyrophyllite is employed as 50 % clay replacement in the ceramics and up to 30 % cement replacement in mortars. Physico-mechanical properties were investigated. The firing shrinkage in the ceramics treated at 1200 °C was reduced by pyrophyllite addition. Pyrophyllite acted as additional pozzolana during cement hydration. Within the microstructure, it formed micro-reinforcement in the shape of crystalline folia, which improves the mechanical properties of ordinary Portland cement, high aluminate cement, and blended cement mortars. The investigation proved the efficiency and suitability of pyrophyllite employed as a substitution for clay in ceramics and a cement replacement in mortars.

AB  - Филосиликатни минерал пирофилит се претежно користи у керамичкој индустрији јер показује високу ватросталност.

AB  - Electrophoretic deposition (EPD) was employed to fabricate composite coatings aimed for orthopedic implants.
Hydroxyapatite (HAP), poly(vinyl alcohol) (PVA) and chitosan (CS) coatings, with or without antibiotic gentamicin
(Gent) were deposited in a single-step process from aqueous suspension, using EPD. Polymer/mineral
composite coatings were formed with the aim to mimic the natural composition of bone tissue, along with
improved coatings antibacterial properties, at the same time serving as a drug carrier, allowing local administration
of antibiotic. Structural and morphological characterization of HAP/PVA/CS and HAP/PVA/CS/Gent
coatings was investigated by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), thermogravimetric
analysis (TG/DTG), and scanning electron microscopy (SEM) proving carbonate-substituted HAP.
The presence of gentamicin contributed to the bactericidal activity of composite HAP/PVA/CS/Gent coating
against Staphylococcus aureus and Escherichia coli. Cytotoxicity studies were performed towards human MRC-5
and mice L929 fibroblast cell lines, and both investigated samples (HAP/PVA/CS and HAP/PVA/CS/Gent)
expressed good biocompatibility, without causing toxic effect on tested cells. Biomineralization potential was
investigated by measuring the alkaline phosphatase activity, demonstrating high potential of HAP/PVA/CS/Gent
to induce the growth of new HAP layer. Therefore, the present investigation proposes the production of nents,
along with antibiotic gentamicin, improving the antibacterial coatings’ properties.

AB  - The essence of this paper is to present the effect of adding TiO2 and SrO to the crystallization characteristics of polyphosphate glasses. The crystallization of glasses has been studied by using DTA, HSM and XRD methods. Sintered phosphate glass-ceramics containing bioactive β-CaP2O6 and β-Ca3(PO4)2 phases were successfully prepared. The increasing presence of Sr (1-5 %), as well as Ti at the expense of phosphate mole fraction in polyphosphate bioactive glass increases the density of these glasses, transformation temperature and resistance to crystallization.

AB  - The goal of this research is to investigate the effect of SrO and La2O3 addition on the crystallization characteristics and sintering behavior of polyphosphate glasses. Differential scanning calorimetry (DSC), hot stage microscopy (HSM), X-ray diffraction (XRD), and scanning electron microscopy (SEM) methods were used to investigate the crystallization and sintering behaviors of glasses. The addition of SrO and La2O3 (1 or 5%), at the expense of phosphate mole fraction in polyphosphate bioactive glass, raises the characteristic temperature of glasses, and resistance to crystallization. Furthermore, the temperature of maximal shrinkage increases with the addition of SrO and La2O3. Surface crystallization is the dominant mechanism of crystallization in all samples. All glasses show complex crystallization leading to the formation of several crystalline phases. Sintered phosphate glass-ceramic containing bioactive beta-CaP2O6, alpha-Ca-3(PO4)(2,) and beta-Ca-3(PO4)(2) phases were successfully prepared.

AB  - This paper presents the results of laboratory tests of the valorization possibility of Pb-Zn slag "Smelter" -Veles, by gravity concentration. It is an inhomogeneous raw material that has a significant content of non-ferrous metals, primarily Pb, Zn and Cu, as well as the presence of precious metal in the form of Ag. The contents of the mentioned non-ferrous metals vary from a few percent to over 10%. The content of silver also varies from a few grams per ton to as many as tens of grams per ton of technogenic raw materials. Mineralogical analysis of the products of the grinding experiment by size classes determined that the useful components from Pb-Zn slag "Veles" are free at grinding fineness of -0.1 + 0.00 mm. Thus, the prepared technogenic raw material was subjected to magnetic separation and gravitational concentration processes. In this paper, only gravitational concentration is treated. It was decided to perform the gravitational concentration of the individual size classes on the Wilfley 13 shaking table, with the selected table surface for small classes and sludges. The obtained results of gravitational concentration of different size classes show that there was a separation of individual components into separate products.. This operation of the lead separation into concentrate (ΔH fraction) and silver in lead concentrate (ΔH fraction) was relatively successful, while the separation of zinc and copper in concentrate (ΔH fraction) gave slightly worse results. The best results in terms of content of Pb, Zn, Cu and Ag in concentrate (ΔH fraction) were achieved for the largest class (-100 + 75 μm) where the content of Pb in this product is 8.44%, zinc 7.42%, copper 0.77% and silver 125 g/t. In all other concentrates (ΔH fractions) obtained from smaller size classes, lower contents of non-ferrous metals and silver in them were obtained.

AB  - In this research, preliminary investigations of the influence of mechanical energy during the
milling process on a sample of natural zeolite were performed. Activation was performed in a
mill with a ceramic vessel and ceramic balls for 15, 30 and 60 minutes. The XRD method was
used to determine the phase composition. The XRD patterns were obtained on a Philips PW-
1710 automated diffractometer using a Cu tube operated at 40 kV and 30 mA. All the XRD
measurements were performed at room temperature in a stationary sample holder. Crystallite
domain size were calcuclated using SiroQuant v4 software. The mineral composition of the analyzed sample is as follows: clinoptilolite-heulandite zeolite types, smectite/chlorite
minerals, quartz, feldspars, mica, and irregularly interstratified clay minerals. Crystallinity
degree of all present phases decreases with activation time in comparison to the non-activated
sample. Crystallite domain size for diffration maximum (020) of non-activated sample was
533 Å (FWHM 0.240 o), and decreases with acitivation time to 202 Å (FWHM 0.275 o) for
sample activated 60 min.

abstract = "In this research, preliminary investigations of the influence of mechanical energy during the
milling process on a sample of natural zeolite were performed. Activation was performed in a
mill with a ceramic vessel and ceramic balls for 15, 30 and 60 minutes. The XRD method was
used to determine the phase composition. The XRD patterns were obtained on a Philips PW-
1710 automated diffractometer using a Cu tube operated at 40 kV and 30 mA. All the XRD
measurements were performed at room temperature in a stationary sample holder. Crystallite
domain size were calcuclated using SiroQuant v4 software. The mineral composition of the analyzed sample is as follows: clinoptilolite-heulandite zeolite types, smectite/chlorite
minerals, quartz, feldspars, mica, and irregularly interstratified clay minerals. Crystallinity
degree of all present phases decreases with activation time in comparison to the non-activated
sample. Crystallite domain size for diffration maximum (020) of non-activated sample was
533 Å (FWHM 0.240 o), and decreases with acitivation time to 202 Å (FWHM 0.275 o) for
sample activated 60 min.",

AB  - Deposits of zeolite tuffs, rich in minerals of the heylandite-clinoptilolite series, in Serbia are
spatially and genetically related to volcanogenic-sedimentary series of sedimentary basins and
were formed as a product of devitrification of volcanic glass. Zeolite minerals in sedimentary
rocks of Neogene age are found in association with volcanic and volcaniclastic rocks. The
lacustrine or marine environment had a great influence on the diagenesis of sediments and the
formation of clinoptilolite at the expense of volcanic glass. In this paper, a preliminary model of
the formation of zeolite deposits in the Tertiary basins of Serbia is presented, through the
processing of all elements of the genetic model.

AB  - УВОД и ЦИЉЕВИ: Услед високих нивоа производње и употребе пластике узрокованих
индустријским развојем, копнена околина садржи алармантне количине одбачених отпадних
пластичних материјала. Једном када доспеју у природу, они подлежу деградационим процесима,
разлажући се на микроскопске фрагменте, познатије као микропластике (МП). МП се дефинишу као
пластични остаци мале величине (< 5 mm) који потичу из различитих извора као што су производи
за личну негу, хабање гума, различите пољопривредне активности, таложење атмосферских
честица, клизишта итд. Земљишна станишта последично постају једно од доминантних басена за
депоновање МП. Токсични ефекти присуства МП у животној средини су бројни. Штавише,
захваљујући јаком капацитету адсорпције, МП би могле коегзистирати са другим загађивачима као
што су тешки метали и органске честице, што представља нови еколошки ризик. Присуство МП је
откривено у екосистемима у којима готово да нема људске активности - дивљим областима
Северне Америке, планинским шумама Пиринеја, па чак и на врху Монт Евереста. Овај рад је имао
за циљ да истражи садржај микропластике у земљишту које окружује Специјални резерват природе
Засавица, указујући на значај овог свеприсутног загађивача који негативно утиче на квалитет
земљишта, живи свет и ланац исхране.
МАТЕРИЈАЛ и МЕТОД: Узорци земљишта су прикупљани помоћу лопате од нерђајућег челика и
текстилних врећа, на травнатој површини у близини Специјалног резервата природе Засавица, на
дубини од 0-20 cm. Узорци су сушени на ваздуху две недеље и просејани кроз сито од 2 mm. Након
просејавања, узорци су сушени на 60˚C у пећи до константне тежине, а затим су мерена три
репликата од укупно 15 g узорка за анализу. На почетку је земљиште третирано са 60 ml 30% H2O2
како би се разорила органска материја земљишта. Како би се постигла боља екстракција МП,
суспензија је подвргнута ултразвучном третману у трајању од 10 минута, имајући у виду да МП
имају тенденцију да буду инкорпориране у агрегате земљишта. Након тога, дигестија је настављена
на 60˚C током 24h. Изолација МП извршена је методом раздвајања по густини. Суви остатак
земљишта који је остао након дигестије прекривен је засићеним раствором NaCl. Густина раствора
NaCl била је 1,2 g cm-1. Суспензија је стављена у ултразвучно купатило на 15 минута и остављена
преко ноћи како би се честице могле редистрибуирати по густини. Горњи слој супернатанта је
филтриран кроз Whatman стаклени филтер (величина пора 1,6 µм, пречник 25 mm). МП су
посматране и пребројане помоћу поларизационог микроскопа (Carl Zeiss Jena Pol-U).
РЕЗУЛТАТИ и ЗАКЉУЧЦИ: У складу с резултатима, узорци земљишта су садржали 800 честица по
kg земљишта, односно у измерених 5 g земљишта у просеку смо нашли 4 честице. Преовлађујући
облици МП били су фрагменти, док је величина била у распону од 50-500 µм. Боја честица је била
бела/провидна. Претпостављени доминантни извори остатака МП на овом подручју, које се сматра
незагађеним, могли би бити производи за свакодневну употребу, као што су амбалажа за храну и
пиће, козметички производи, текстил, гуме итд. Претпоставља се да индустрија и пољопривреда не
доприносе у значајној мери доказаном присуству МП. Метода која користи засићени раствор NaCl
даје информације само о честицама полимера са густином мањом од 1,2 g cm-1. Стога се очекује
да ће екстраховане честице бити остаци полимера као што су LDPE и HDPE (полиетилен ниске и
високе густине), PP (полипропилен), ABS (акрилонитрил бутадиен стирен), PC (поликарбонат),
HIPS (полистирен високог утицаја), или PA (полиамид). Јасан увид у утицај МП на екосистем тек
треба да се испита. Будућа истраживања биће усмерена на утицај МП на важна физичко-хемијска
својства земљишта и живи свет, одређивање типа и карактеризација МП и њеног главног извора
порекла на проучаваном подручју, како би се у будућности примениле одговарајуће мере за
смањење загађења пластиком.

AB  - Microplastics (MPs) are a newly acknowledged, pervasive pollutants found even in distant Earth
areas and represent a matter of global concern. This study inspects, for the first time, microplastic
content in terrestrial environments in the city of Bor, known as one of the most polluted industrial
cities in Serbia. Soils from the park in the II kilometer and the periphery of the Bor (Brezonik
settlement) were collected and analyzed. Plastic particle extraction from the soil matrix was
performed using the flotation method based on density separation. MP content differed significantly
between the two sites. Urban soil contained around 3800 items kg-1
, while suburban held 600 particles
per kilogram. The outstandingly high difference likely originates from the distinction in the
anthropogenic activity levels of the two localities. There was no notable difference in appearance. All
extracted items were white to transparent fragments. The morphological shape of plastic particles
indicated defragmentation as a governing origin source. Future investigations should be concentrated
on the MPs' correlation with other contaminants, namely heavy metals, and the eventual recognition
of MP`s role as the metal pollution vector in the investigated area

AB  - A low-cost waste biomass generated from a food industry, apricot shells, was subjected to alkali modification in order to compare morphology, crystalline structure and thermal stability of native and modified biomass, accompanied by their cellulose-rich fractions. The surface morphology and structure of compared samples were analysed by the scanning electron microscopy (SEM) and mercury porosimetry. Furthermore, Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD) and thermal analysis (TG/DTA) were applied. The results have shown that after alkaline treatment, inter- and intra-particle porosity in the material rises, resulting in increase of the total surface area. The XRD diffractograms showed that crystallinity index increased together with crystallite size, suggesting that modified sample has more ordered crystalline structure than native sample (also confirmed by the FTIR analysis). Although the cellulose-rich fraction extracted from the alkali-modified sample showed higher thermal stability, the overall thermal analysis revealed that alkali-modified biomass has lower thermal stability than the native sample. This indicates that this type of modification will improve the fuel properties of this lignocellulosic biomass and imply its possible application in energy recovery process.

AB  - This paper examines the effects of structural-textural characteristics of sulfide minerals on their leaching from polymetallic concentrates with sulfuric acid and hydrogen peroxide solutions. The polymetallic concentrate was obtained by flotation of polymetallic ore from the Rudnik deposit in Serbia. X-ray diffraction (XRD), qualitative and quantitative mineralogical, scanning electron microscopy (SEM/EDX), and chemical analyses were used to characterize the polymetallic concentrate and leach residue. The polymetallic concentrate contained chalcopyrite, galena, sphalerite, pyrrhotite, and quartz. The total content of sulfide minerals was 69.5%, and the occurrence of free sulfide mineral grains was about 60.9%. The comprehensive thermodynamic analysis was done by HSC Chemistry (R) package 9.9.2.3 to determine optimal experimental leaching conditions. Chalcopyrite, sphalerite, and pyrrhotite oxidized during leaching, and dissolution occurred. The oxidized galena remains in the solid residual as insoluble anglesite. Also, elemental sulfur and unleached minerals of copper, zinc, and iron were found in the leach residues. It was found that the structural assembly of sulfide minerals in the leach residue is very favorable and that undissolved sulfide grains are primarily present in free form. Accordingly, there was no reason to reduce the leaching rate with time. The presence of elemental sulfur and anglesite formed in the leaching process and precipitated on the surface of mineral grains was confirmed by XRD, quantitative and qualitative mineralogical analysis, and SEM/EDX.

AB  - Zeolites are a group of natural and artificial inorganic compounds, which have specific physicochemical properties appropriate for industrial application. These minerals make a specific group of alumosilicates within tectosilicates because of their origin, chemical compositions, structural characteristics and application. This paper presents the results of mineralogical and crystallographic examination of zeolite tuff samples from the Toponica deposit. The deposit of zeolite tuff ""Toponica"" is located in the extreme eastern part of Kosmet near Kosovska Kamenica. The immediate geological structure of the zeolite tuff deposit consists of the Lower Miocene (M) clayey sandstone, the horizon of the white zeolite tuff and the reclassified Miocene clays, clays and gravel. The basic mineral composition is the mineral clinoptilolite-Ca from the heylandite series.
