Potentiostatic oxidation of AgCu50 alloy in alkaline solution in the presence of chlorides
(Pergamon-Elsevier Science Ltd, Oxford, 2013)
SEM and EDS analyses of AgCu50 alloy were performed after potentiostatic oxidation in an alkaline solution in the presence or absence of chloride ions. Oxidation in pure alkaline solution was favoured on the portion where ...
Low-temperature Ni-As-Sb-S mineralization of the Pb(Ag)-Zn deposits within the Rogozna ore field, Serbo-Macedonian Metallogenic Province: Ore mineralogy, crystal chemistry and paragenetic relationships
(Elsevier, Amsterdam, 2015)
The Rogozna ore field (ROF) belongs to the Serbo-Macedonian Metallogenic Province (SMMP), and covers a part of the western Dinarides rim and the Vardar ophiolite zone, situated within the Neogene volcanogenic-intrusive ...
Kinetics of chalcopyrite leaching by sodium nitrate in sulphuric acid
(Elsevier Science Bv, Amsterdam, 2009)
Hydrometallurgical processes offer a great potential for treating chalcopyrite ores and concentrates, and it results in increased metal recoveries and reduced air pollution hazards. In recent years interest for application ...
Hydrothermal carbonization of Miscanthus x giganteus: Structural and fuel properties of hydrochars and organic profile with the ecotoxicological assessment of the liquid phase
(Pergamon-Elsevier Science Ltd, Oxford, 2018)
In this study, hydrothermal carbonization (HTC) was employed for thermochemical conversion of energy crop Miscanthus x gigcuiteus GREEF et DEU. The effect of process temperatures, in the range between 180 and 220 degrees ...
Utilization of Phosphate Rock from Lisina for Direct Application: Release of Plant Nutrients in the Exchange-Fertilizer Mixtures
(Amer Chemical Soc, Washington, 2014)
This study examined the possibility of direct application of phosphate rock (PR) from Lisina deposit, in a mixture with natural clinoptilolite (Cp) and clinoptilolite partially saturated with ammonium ions (NH4Cp). Solution ...
A nappies management by-product for the treatment of uranium-contaminated waters
(Elsevier, Amsterdam, 2021)
The direct disposal of municipal solid waste such as nappies to the environment may create serious pollution problems. Based on the circular economy and waste management concepts, the conversion of nappies and/or their ...
Optimization of the process of Cu(II) sorption by mechanically treated Prunus persica L. - Contribution to sustainability in food processing industry
(Elsevier Sci Ltd, Oxford, 2017)
This paper presents an eco-friendly approach for minimizing heavy metal pollution, offering food waste valorization and energy source at the same time. It focuses on Cu(II) sorption by low cost sorbent developed by mechanical ...
Mineralogy and genetic features of the Cu-As-Ni-Sb-Pb mineralization from the Mlakva polymetallic deposit (Serbia) - New occurrence of (Ni-Sb)-bearing Cu-arsenides
(Elsevier Science Bv, Amsterdam, 2017)
(Ni-Sb)-bearing Cu-arsenides are rare minerals within the Mlakva and Kram mining sectors (Boranja ore field) one of the less-known Serbian Cu deposits. (Ni-Sb)-bearing Cu-arsenides were collected from the Mlakva skarn-replacement ...
The assessment of maturation changes of humic coal organic matter - Insights from closed-system pyrolysis experiments
(Elsevier, Amsterdam, 2016)
The artificial maturation changes of the humic coal organic matter (OM) from late diagenesis to the semianthracite stage of coalification were investigated using the closed-system pyrolysis. Two extracted coal samples, a ...
Influence of surface coverage of kaolin with surfactant ions on adsorption of ochratoxin A and zearalenone
(Elsevier, Amsterdam, 2021)
A natural kaolin from Serbia was modified with different amounts of octadecyldimethylbenzyl ammonium (ODMBA) - (25, 50 and 90% of kaolin cation exchange capacity). Samples were denoted as OKR-25, OKR-50 and OKR-90. Several ...
