AB  - U radu su prikazani rezultati istraživanja iz oblasti usitnjavanja, sakupljani duži niz godina, u Institutu za tehnologiju nuklearnih I drugih mineralnih sirovina. Poznato je da se područja sa frekfencijama preko 3•1011 do 3•1014 Hz nalaze u elektromagnetnom spektru infracrvenog i daleko infracrvenog emitovanog ili apsorbovanog zračenja. U radu su prikazani rezultati kada se materijal i kugle u mlinu nalaze na jednoj od pomenutih frekfencija, što nam omogućava da pomoću Borovog uslova frekfencija pristupimo izračunavanju emitovanih i apsorbovanih molarnih energija. Polimorfne promene materije pri usitnjavanju su promene izazvane fizičkim procesima, odnosno emitovanjem određene količine energije od strane mlina I adsorbovanjem tih energija od strane materijala. Izvršen je pokušaj da se odrede nivoi tih energija. Prikazani rezultati pokazuju da sve jedinke u mlinu pretrpe lokalni pritisak i tada na njima, delimično ili u celini, dolazi do polimorfnih promena materije menjajući fazna stanja i kristalnu strukturu iste. Na zrnima minerala na veoma ograničenim mestima po površini (10-3 do 10-5 cm2) i u kratkim vremenskim periodima trajanja (10-4 s) dolazi do povećanja temperature čak do 1000 C što su autori iz reference [3] nazvali magma plazma modelom slika 1. Rad prikazuje praćenje polimorfnih promena materija preko promena njihovih termodinamičkih veličina. Takođe, postoje i velike razlike polimorfnih promena minerala u zavisnosti od mineraloškog oblika u kojem se materija nalazi.

AB  - Velike količine flotacijske jalovine stvaraju se u Srbiji (preko 20 Mt), kao i u svetu (20.000-25.000 Mt). Zbog zaostalih teških metala (Pb, Cu, Fe i Zn...) ona predstavlja potencijalno opasni otpad koji bi trebalo zbog vrednosti plemenitih i obojenih metala u njoj reciklirati. Na Rudniku „Rudnik“ svake godine se generiše oko 250.000 t, flotacijske jalovine, od 1953. god. oko 11 Mt. Naučno istraživačkim radom i obavljenim ispitivanjima u okviru Projekta-REASONING (2024.-2026.) dobiće se rezultati i osvojiće se nova inovativna rešenja i znanja čija će implementacija omogućiti osvajanje tehnoloških postupaka reciklaže i prerade flotacijske jalovine Rudnika “Rudnik”.

AB  - Velike količine prašine iz EAF peći se stvaraju u Evropi (1,3Mt), kao i u svetu (8,764Mt). Zbog visokog sadržaja Fe i Zn, čiji sadržaj često dostiže ukupno između 50 i 60 tež.%, EAF prašina je oduvek bila interesantna za reciklažu. Do sada, najčešće primenjivana metoda prerade EAF prašine je pirometalurški proces ekstrakcije Zn u Waelz pećima (85% tržišnog učešća). U radu je predstavlјen EIT Raw Materials projekat: RIS-DustRec-II, koji ima za cilј razvoj inovativnih tehnologija za odvajanje, ponovnu obradu i korisnu upotrebu svih komponenti EAF i CF prašine iz peći, kako bi se smanjila količina toksičnog otpada i postigla nulta vrednost. –što je cilj za otpad u EU. Urađene su I predstavlјene hemijske, XRD i SEM analize na dva odabrana uzorka prašine EAF i CF peći iz Italije.

AB  - Biochar continues to strengthen its presence in many new industries with its new applications, which are full of scientific and business news. A flurry of activity has sprung up around this carbon-based material, produced from biomass, following its use in water treatment, energy production and animal husbandry. In any new industry, process and product development, as well as feasibility studies, are very important for the product to come to market. This is especially true when it comes to biochar. Besides being in its infancy as an industry, biochar itself presents a number of challenges that make various tests necessary. Many properties affect the quality and performance of biochar products (pore size, cation exchange, electro- conductivity...) and will most likely vary depending on the starting material and the method of obtaining. Biochar can be made from a very long list of biomass materials. Although the above creates opportunities for industries that abound with highly adaptable products, it can still make biochar unpredictable, given that each starting material affects the characteristics of the final products differently.

AB  - This paper describes a part of the experimental procedure for testing the performance of grinding media (steel balls) during the smelting slag milling, as well as the modeling procedure and model results that predict the consumption of balls under given experimental conditions. Firstly, the most suitable mineral raw material for testing the durability of the grinding media was defined. In laboratory conditions, it was determined that it is most expedient to use slag from the melting process of Pb-Zn concentrate for testing. The coarse moisture content was determined on the initial slag sample, while the particle size composition and Bond work index were determined on the crushed slag samples. In accordance with the characteristics of the raw material, the technical-technological parameters of the system for wet grinding of slag were defined, in which the balls durability test was performed. The obtained results showed that the consumption of grinding media is about 1 kg/t of slag. Six ANN models, developed on the basis of experimental results, showed good predictive abilities when it comes to stel balls consumption. As a result of modeling, high correlation coefficients were obtained, the value of which was about R = 0.99.

AB  - Powdered gypsum products were the standard for agricultural gypsum for many years, but as growers look to maximize
their return on investment, they are increasingly turning toward pelletized gypsum – a premium alternative. Pelletized
gypsum offers several significant advantages over other forms of gypsum such as powdered or ultra-fine gypsum, these
advantages will be discussed in the paper. This has led to increased grower adoption and a greater demand for fertilizer
and soil amendment producers to offer gypsum in a pelletized form. Producers are also finding that they stand to gain a
few benefits from offering a pelletized product as well.

AB  - Smelting slag from "Topionica" -Veles (Northern Macedonia) owned by the company "KEPS MONT GROUP" Skopje is a potentially valuable raw material. Tests have shown that this is an inhomogeneous raw material with significant contents of non-ferrous metals, primarily Pb, Zn, Cu, and silver is present from precious metals. Mineralogical tests have shown that the composition of man-made raw materials is very complex and consists of amorphous and mineral phases, ie the microscopic method showed the following composition: amorphous phase, lead alloys, zinc alloys, vistite (FeO), sphalerite, galena, cerusite, elemental silver, elemental copper, elemental iron, magnetite, spinel, rutile, hematite, troilite (FeS). The most common amorphous phase (glass matrix) of spinel, silicate and mixed (spinel-silicate) composition is in the sample, while vistite, which occurs in the form of skeletal separations in the glass matrix, is significantly less represented. Based on SEM analysis (scanning electron microscopy), these are Fe-Mn-Zn spinels. Lead and zinc alloys are the most common. Mineralogical analysis by size classes determined that useful and unuseful components of Pb-Zn slag "Veles" were released at a fineness of -0.1 + 0.00 mm, so that magnetic separation tests were performed on this size class. Magnetic separation was performed on two devices, a Davis wet analyzer and a dry disk magnetic separator. By magnetic separation on a Davis magnetic separator, a small degree of iron concentration in the MF (1,134) relative to the input was obtained, with low iron distribution in the magnetic fraction of 16.79%. Magnetic separation on a dry disk magnetic separator also yielded a low degree of iron concentration in the magnetic fraction with distribution of 55.38% and 44.62% in the non-magnetic fraction.

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.

abstract = "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  - This paper presents the results of testing the possibility of using limestone from the „Međeđe“ - Nikšić
deposit in different industries. During the examination, the coarse moisture, chemical composition,
granulometric composition, bulk and particle density, degree of whiteness, oil and water absorption,
granulometric composition of micronized samples and specific surface area were determined. All tests
were performed on 8 samples taken from different parts of the deposit and the mean values of the
obtained results are presented here. Based on the physico-chemical characteristics, it can be stated that
this limestone has a high content of CaO and CaCO3 of 99.01%, as well as a relatively low content of
MgO of 0.32% and a low content of SiO2 of 0.26% and alkali and R2O3, with also low content of heavy
metals, which is very favorable for limestone. With these physico-chemical properties, this limestone
can be used in the following industries: paints and varnishes, paper, rubber and PVC, foundry and
foundry industry, sugar industry, metallurgical purposes, glass production, animal feed production and
mineral fertilizer production. A serious defect of „Međeđa“ limestone is the low degree of whiteness,
which does not exceed 89.6%, which prevents its use in the pharmaceutical and chemical industries,
while the relatively high content of K2O, Fe and Mn prevents its use in calcification of acid soils.

AB  - This paper presents results of investigations of the possibility of us-ing “Vučića Brijeg”-Ulcinj limestone (Republic Montenegro) as filler in vari-ous 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 car-bonate raw materials with high CaCO3 content of 97.87%, as well as MgO con-tent of 1.04% (2,18% content of MgCO3 ) and low silicate content (SiO2 0.40%). Its quality satisfies requirements of standards on using of calcium carbonate as filler in industry of paints and coatings; paper industry; rubber and PVC industry; glass industry; production of mineral fertilizers; foundry industry; sugar industry and metallurgy. Due to the low degree of whiteness (81.65%) „Vučića Brijeg” limestone cannot be used in pharmaceutical and cosmetics industry. Due to rela- tively high content of heavy metals, Pb (55 ppm), Cu (10 ppm), Ni (23ppm) and Cd (5 ppm), “Vučića Brijeg”-Ulcinj limestone cannot be used, in production of cattle feed and for neutralization of acidic soils.

AB  - The paper investigates the composition and procedures for the production of refractory coatings based on cordierite for the protection of parts of equipment in metallurgy and mining. An ultrasonic vibration method with a stationary sample according to the ASTM G32 standard was used to determine the resistance properties of the obtained protective coatings. The aim of the study was to determine the quality of coatings and the possibility of application for the protection of metal surfaces in conditions of cavitation, wear and corrosion. The change in the mass of the samples as a function of cavitation time was monitored. Cavitation velocity was determined as an indicator of coating resistance under cavitation loads. The occurrence and development of coating surface damage were monitored using a scanning electron microscope. Based on the value of cavitation velocity and analysis of surface damage morphology, cavitation resistance of the coating was determined. The results showed a satisfactory degree of resistance to cavitation of the tested refractory coatings based on cordierite and the possibility of their application for the protection of parts of equipment that will be exposed to cavitation loads during exploitation.

Sva ispitivanja su obavljena na 8 uzoraka uzetih iz različitih delova ležišta a u radu su prikazane srednje vrednosti dobijenih rezultata.

AB  - This paper presents the results of experiments performed to determine how the quantity of the binder (bentonite) and the parameters of the laboratory roll press affect the quality of the briquettes obtained from limestone powder. These experiments aim to examine the conditions in which limestone briquettes are formed and to determine their use for agricultural purposes. During the experiments various mass fractions of bentonite was added to limestone (from 1 to 10 %), while the force of roll press drums ranged from 2 to 25 kN. The briquettes have been tested by applying scanning electron microscopy (SEM), differential thermal and thermo-gravimetric (DTA/TG) analyses, X-ray diffraction (XRD) and Fourier-transform infrared spectroscopy (FTIR). Bentonite distribution was found to be uniform within the compact briquette structure. Formation of new compounds was not evidenced. The experiments also demonstrated that during briquetting, limestone properties remain unchanged, the changes are only physical, water solubility is not reduced, mechanical properties (impact resistance, compressive strength and abrasion resistance) are satisfactory by the transport and storage terms if the binder mass fraction is over 5% and the briquetting force exceeds 10kN and finally there is no loss due to wind dispersal during application. The only downside of the "green" briquettes obtained is the time required for their complete disintegration if totally immersed in water.

During the experiments various mass fractions of bentonite was added to limestone (from 1 to 10 %), while the force of roll press drums ranged from 2 to 25 kN. The briquettes have been tested by applying scanning electron microscopy (SEM), differential thermal and thermo-gravimetric (DTA/TG) analyses, X-ray diffraction (XRD) and Fourier-transform infrared spectroscopy (FTIR). Bentonite distribution was found to be uniform within the compact briquette structure. Formation of new compounds was not evidenced. The experiments also demonstrated that during briquetting, limestone properties remain unchanged, the changes are only physical, water solubility is not reduced, mechanical properties (impact resistance, compressive strength and abrasion resistance) are satisfactory by the transport and storage terms if the binder mass fraction is over 5% and the briquetting force exceeds 10kN and finally there is no loss due to wind dispersal during application. The only downside of the "green" briquettes obtained is the time required for their complete disintegration if totally immersed in water.",

AB  - This paper is focused on the preparation procedures, using a talc-based filler, to improve the rheologic properties of the lost foam refractory coatings. Talc, with grain size of 40 .m, was mechanically activated in a vibration mill over the following times: 10, 20 and 30 min. Depending on the time required for the mechanical activation, the change in the filler grain size and shape was analysed along their effects on the talc-filled lost foam coating dispersion ability and stability. In order to characterize the filler, the following methods were used: X-ray diffraction, scanning electron microscopy and optic microscopy. The coating composition was tuned by choosing the suitable grain size and shape factor of the activated filler. In addition, different coating components (additives, solvent) were applied to alter the coating generation procedure. It was shown that the application of this type of the lost foam refractory coatings - water-based coatings - have a positive influence on quality of the aluminium alloy castings, which contributes to reducing the cost of cleaning and processing of the castings. Also, alcohol-based refractory coatings with talc-based activated fillers were tested and used to have the castings produced in the sand moulds.

AB  - This paper presents the results of physico-chemical characterization of both the initial samples of lithotamnian
limestone and seaweed (Ascophyllum Nodosum), and the products of aggregation of their mixtures in different
ratios by the pelletization process. The initial samples were waste limestone from filter plants and dried seaweed.
The final product of the pelletization process should serve the needs of agriculture as a means of biostimulation
and can also be used in raising the pH levels of acidic soils. Several different pellet formulations were obtained by
the process of discontinuous pelletization, and also by using a simulation of the continuous pelletization process on
a pelletization plate. Tests of the mechanical properties of the pellets showed that the best results are shown by the
pellets of the 4K sample, which were obtained by a continuous pelletization process with a mutual ratio of seaweed
and limestone of 70:30%.

AB  - This paper presents results of investigations of the possibility of using “Pješivački Do”-Danilovgradlimestone 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 high CaCO3 content of 98.65%, as well as low MgCO3 content of 0.95% and low silicate content (SiO2 0.23%). Its quality satisfies requirements of standards on using of calcium carbonate as filler in industry of paints and coatings; paper industry; rubber and PVC industry; in production of cattle feed; glass industry; production of mineral fertilizers and sugar industry. Due to the low degree of whiteness (87,6%) Pješivački Do”limestone cannot be used in pharmaceutical and cosmetics industry. Due to relatively high content of Cr (10 ppm) as heavy metal, content of S (0,19%), as well as biogenic elements P2O5 (0.030%), “Pješivački Do” limestone cannot be used in, foundry industry and metallurgy and for neutralization of acidic soils.

AB  - Since the late seventies of twentieth century geopolymers have been investigated as a new type of aluminosilicate binders which will eventually replace traditional cement based structural materials. Geopolymers are the three-dimensional synthetic inorganic polymers, which contain amorphous and semi-amorphous crystal microstructures. Hybrid binders are structural materials which combine alkali activated raw materials and cement in its mixdesign. In this paper the characteristics of bentonite, which are important for its application in geopolymers and hybrid cement binders, were thoroughly investigated in order to evaluate its proneness to alkali activation. Bentonite samples from three different deposits were submitted to detail testing. Elaborate physico-chemical and mineralogical characterization was The Nineth Serbian Ceramic Society Conference »Advanced Ceramics and Application« September 20-21, 2021 Serbian Academy of Sciences and Arts, Knez Mihailova 35, Belgrade, Serbia 83 conducted. Determined moisture contents in bentonite samples were from 20.54 % to 24.15 %. Hygroscopic moisture was in range 7.99 - 8.99 %, and specific mass was in range 2.42 - 2.52 g/cm3 . Grain-size analysis of the bentonite samples was conducted using Sympatec laser sizer. Mineralogical analysis highlighted smectite, α-crystbalite, quartz, and feldspar as the most aboundant mineral phases. DTA/TG analyses were conducted to monitor thermal behavior of the bentonite samples in thermal range 20 – 1000 °C. Cation exchange capacity, CEC, (Ca2+, Mg2+, Na+ , and K+) was also conducted. Obtained total CEC values were from 66.16 meq/100g to 78.97 meq/100g. Plasticity of bentonite samples was determined using Atterberg – Casagrande methodology. Also Moisture absorption coefficient (using Enslin –Neff methodology), pH values and dioxin content in samples were tested. It was determined that investigated bentonite samples showed high potential for application in construction materials, i.e. geopolymers and hybrid binders.
