An alternative route for valorization of valuable metals from jarosite residue / Alternativna metoda za valorizaciju vrednih metala iz jarosit ostatka
(Savez inženjera i tehničara Srbije, Beograd, 2019)
This paper aims to consider the treatment of jarosite residue using a different reducing agents, aluminum, magnesium, and carbon. The jarosite residue is not standard-it contains higher amounts of Pb and Ag, as well as in, ...
The effect of mechanical activation on synthesis and properties of MgAl2O4 ceramics
(Elsevier Sci Ltd, Oxford, 2019)
Magnesium aluminate, MgAl2O4 and other alumina-based spinels are ceramics with high hardness, high melting point and mechanical strenght. Spinels can also be used as dielectrics in microwave applications. The goal of this ...
Cavitation resistance of composite polyester resin/basalt powder
(Society for Structural Integrity and Life, Institute for Material Testing, 2019)
The paper presents the results of research on cavitation resistance of the composite based on unsaturated polyester resin and basalt powder, as reinforcement. Basalt powder was obtained by grinding and micronising basaltic ...
