Leaching behavior of sulfur concrete with fly ash used for removal of heavy metals from wastewater
(Belgrade : Mining institute BelgradeAcademy of Engineering sciences of SerbiaUniversity of Belgrade, 2015)
When considering the materials that have become waste in a technological process, one way of their immobilization is for the production of certain new materials. The basic fact is to provide the environmentally acceptable ...
Possibility of using diatomaceous earth from Kolubara and Vesje deposits for production of beer filter aids
(Belgrade : Mining Institute BelgradeAcademy of Engineering Sciences of SerbiaUniversity of Belgrade, 2015)
Diatomaceous earth is a non-metallic mineral raw material composed of skeletal remains of
single-cell water plants, known as diatomite. Owing to quite complex structure of skeletal diatomite
with numerous fine microscopic ...
Kinetics of copper adsorption from wastewater by lignite
(Sofia, Bulgaria : Publishing House “St. Ivan Rilski”, 2013)
Kolubara lignite was used as a natural and low cost adsorption material for removal of copper (Cu2+) from the aqueous solutions. As a method, batch adsorption procedure was applied. Results show that domestic lignite is ...
Anisotropy of refractory concrete subjected to the thermal shock by using the surface analysis
(Bor : University of Belgrade - Technical Faculty in Bor, 2013)
Monitoring and analysis of the material anisotropy during the thermal shock of the refractory concrete was studied. The material was alumina based low cement castable pre-treated at 1300°C for 3 hours. Water quench test ...
Adsorption properties of TENT fly ash in removal of copper from wastewater
(Bor : University of Belgrade - Technical Faculty in Bor, 2013)
The objective of this study was to monitor the behavior of fly ash originated from the power plant Nikola Tesla as a low cost absorbent for removal of copper ions from synthetic aqueous solutions. Fly ash, a potentional ...
Removal of copper, cadmium, and zinc from the mine wastewater in RTB Bor by low cost adsorbent fly ash
(Bor : University of Belgrade - Technical Faculty in Bor, 2013)
Using fly ash, lignite and mixture of lignite and fly ash for the removal of Cu, Cd and Zn from the acid mine wastewater was studied. The batch and dynamic experiments were conducted. Analysis of mine wastewater proved ...
Adsorption isotherms of removing copper from aqueous solutions by low cost adsorbent-lignite
(Sofia, Bulgaria : Publishing House “St. Ivan Rilski”, 2013)
Serbian lignite from ’’Kolubara’’ deposit was used as a low cost adsorbent for removal of copper ions (Cu2+) from aqueous solutions. Lignite was subjected to the elementary and technical analysis as well as BET and FTIR ...
Concentration method for the mining wastewater-valorization of the copper
(The Regional Environmental Center for Central and Eastern Europe, 2013)
During the mining process of copper exploitation, a large amount of wastewater is generated. Not only do the copper ions contaminate the water but also represent a great loss for the copper production industry. Negative ...
Environmental influence on service life expectancy of ceramic structures
(Политехпериодика/Politehperiodika, 2015)
During the service life, materials are exposed to environmental influences. The aim of this research is to analyze behavior of sulfur concrete compared to Portland cement concrete in acid environment. It has been shown ...
Energy efficient pulse-reverse regimes of electrodeposition / Energetski efikasni pulsno-reverzni režimi galvanizacije
(Union of Mechanical and Electrical Engineers and Technicains of Serbia (SMEITS)Society for Renewable Electrical Power Sources, 2017)
Pulse reverse power modes are used in order to obtain metal coatings with similar or better characteristics, compared with the coatings produced by constant current. Pulse reverse modes increase production and energy ...
