Crystallization kinetics of K2O·TiO2·3GeO2 glass studied by DTA
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2008)
Kinetika kristalizacije K2O·TiO2·3GeO2 stakla je proučavana primenom diferencijalno termijske analize (DTA). Eksperimenti su izvedeni na uzorcima stakla granulacije LT 0,037mm koji su zagrevani različitim brzinama u ...
Influence of mechanical activation on elelctrical properties of cordierite ceramics
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2008)
Cilj ovog istraživanja je bio da ispita moguće korelacije funkcionalnih svojstava kordijeritne keramike u funkciji od pripreme polazne smeše. Trokomponentni sistem sastava MgO+Al2O3+SiO2 u odnosu 2:2:5 je pripremljen sa ...
To what extent do soft mechanical activation and process parameters increase the efficiency of different zeolite/phosphate rock fertilizer mixtures? (vol 23, pg 1, 2017)

Effect of la2o3 on the structure and the properties of strontium borate glasses
(Savez hemijskih inženjera, Beograd, 2016)
The selected lanthanum-strontium borate glasses were prepared by a conventional melt-quenching technique. The compositions of the investigated glasses were chosen to be: 5.7, 9.5, 14.3, 19.1 mol% for La2O3, 22.9, 19.1, ...
A quick method for bond work index approximate value determination
(Oficyna Wydawnicza Politechniki Wroclawskiej, Wroclaw, 2017)
The Bond work index is a measure of ore resistance to crushing and grinding and is determined using the Bond grindability test. Its value constitutes ore characteristic and is used for industrial comminution plants designing. ...
Treatment of the acidic effluent from a copper smelter by flotation tailings
(Savez hemijskih inženjera, Beograd, 2019)
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 ...
Investigations of quartz raw materials from the locality of Rekovac muncipality
(Savez hemijskih inženjera, Beograd, 2019)
Quality of raw materials, including quartz sand and quartzite, varies from one deposit to another. Furthermore, the material quality determines in which industrial branches it can be used after certain preparation processes. ...
Refinement of waste phosphogypsum from Prahovo, Serbia: characterization and assessment of application in civil engineering
(Mineralogical Soc, Twickenham, 2020)
Two samples collected from the phosphogypsum deposits of the chemical products industry Elixir Prahovo (Serbia) were subjected to a recrystallization experiment performed over several repeated cycles. In these tests, ...
Investigation of mechanism and kinetics of chalcopyrite concentrate oxidation process
(Croatian Metallurgical Society, 2008)
The oxidation process of chalcopyrite concentrate "Rudnik" (Serbia) was investigated by DTA-TG measurements under air conditions in the temperature range of 298 - 1173 K, as well as by XRD analysis of the oxidation products ...
