Conceptual design for treatment of mining and metallurgical wastewaters which contains arsenic and antimony
(Association of Metallurgical Engineers of Serbia, 2012)
This paper presents a preliminary design for treatment of mining and metallurgical wastewaters (MMW) from the basin of antimony 'Zajača', which contains high concentrations of arsenic and antimony. MMW have been investigated ...
The inhibitive effect of ethanolamine on corrosion behavior of aluminium in NaCl solution saturated with CO2
(Association of Metallurgical Engineers of Serbia, 2012)
In this study, the inhibitive effect of ethanolamine on corrosion behavior of aluminium was investigated in 3 wt. % NaCl solution, saturated with CO2. All the experiments were carried out at 20°C. Ethanolamine was added ...
The morphology of ductile cast iron surface damaged by cavitation
(Association of Metallurgical Engineers of Serbia, 2012)
The study was designed to investigate the cavitation behavior of the ductile cast iron with microstructure consisting of spheroidal graphite in a predominantly ferrite matrix with 10% pearlite. The experiments were conducted ...
Thermal and mechanical properties of high alumina low cement castable
(Association of Metallurgical Engineers of Serbia, 2012)
Alumina based low cement castable (LCC) was synthesized and then treated from room temperature to 1600°C. Ultrasonic measurements were applied with the aim to obtain results of longitudinal and transversal ultrasonic ...
Dynamic mechanical properties of aramid fabrics impregnated with carbon nanotube/poly (vinyl butyral)/ethanol solution
(Association of Metallurgical Engineers of Serbia, 2013)
In this study six samples of polyurethane/p-aramid multiaxial fabric forms (Colon fabrics) were coated with 10 wt.% poly (vinyl butyral) (PVB)/ethanol solution with the addition of multiwalled carbon nanotubes (MWCNT). The ...
Analysis of copper losses throughout weak acid effluent flows generated during off-gas treatment in the new copper smelter RTB Bor
(Association of Metallurgical Engineers of Serbia, 2013)
The previous inadequate treatment of off-gas in RTB Bor in Serbia has resulted in serious pollution of the environment and the possibly high losses of copper through the effluent flows. The project of New Copper Smelter ...
The effect of cooling rate of slag from primary copper production in the valorization of copper in the flotation process
(Savez inženjera metalurgije Srbije, Beograd, 2015)
Technological procedure of slow cooling slag from primary copper production is applied in the purpose of copper recovery in the level of 98.5% to blister. This technological procedure is divided into two phases, first slow ...
Kinetics of barite reduction from refractory barite-sulphide ore
(Savez inženjera metalurgije Srbije, Beograd, 2016)
Refractory sulphide-barite ore was reduced with carbon in order to release lead, zinc, and copper sulphide from barite-pyrite base. Mineralogical investigations showed that due to the complex structural-textural relationships ...
Influence of the fabrication process of copper matrix composites on cavitation erosion resistance
(Savez inženjera metalurgije Srbije, Beograd, 2017)
Copper matrix composites reinforced with ZrB2 particles were produced in two ways: by hot pressing (HP) and laser-sintering process. Powder mixture Cu-Zr-B was mechanically alloyed before densification processes. Variations ...
Treatment of dispersed iron-bearing raw materials and modeling of the protection systems against air-pollution
(Association of Metallurgical Engineers of Serbia, 2016)
Based on the analysis of the non-standard iron-bearing raw materials treatment process and the results of real composition measurements of the flue gas, the study of hazards by identification of harmful substances that ...
