Metal pollution determined by pollution indices for sea grass p. Oceanica and surface sediments
(Srpsko biološko društvo, Beograd, i dr., 2015)
Concentrations of Fe, Mn, Cu, Zn, Pb, Ni, Co, As, Co, and Hg in the sea grass Posidonia oceanica and surface sediment samples were determined. Together with P. oceanica, surface sediment samples were collected at eight ...
Potentiality of obtaining mica flotation concentrate from kaolinised granite
(Polska Akad Nauk, Polish Acad Sciences, Warszawa, 2019)
This study shows the results of flotation concentration of mica minerals from kaolinised granite taken from the "Basica bare" deposit - Kobas, Srbac, The Republic of Srpska (B&H). Mineralogical composition of kaolinised ...
Modeling and Prediction of the end of Life Vehicles Number Distribution in Serbia
(Budapest Tech, Budapest, 2016)
The impact of various time-defendant factors on the recycling rate of end-of-life vehicles (ELV) in Republic of Serbia was investigated. Statistical distribution of the frequency of the number of ELV in the year of dismantling ...
Effect of Tempering on Mechanical Properties and Microstructure of a High-Strength Low-Alloy Steel
(Springer, New York, 2014)
The effect of tempering at 450 - 650A degrees C of different duration on mechanical properties and microstructure of a cast low-alloy steel is investigated. The ultimate rupture strength, the yield strength, the elongation ...
Analysis of major, minor and trace elements in surface sediments by x-ray fluorescence spectrometry for assessment of possible contamination of Boka Kotorska bay, Montenegro
(Soc Chemists Technologists Madeconia, Skopje, 2014)
Boka Kotorska Bay is on the UNESCO's World Heritage List. There are no published papers related to the surface sediment pollution of the Bay. For the first time, elements were measured in surface sediments at nine locations ...
The effect of CaO and MgO addition and cooling rate on stability of slag obtained after jarosite and neutral leaching residue treatment in the Waelz process
(Oficyna Wydawnicza Politechniki Wroclawskiej, Wroclaw, 2018)
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 ...
