Samples of concrete contain various waste materials, such as iron particulates, steel balls of used ball bearings and slags from steel industry were assessed for their anti-radiation attenuation coefficient properties. The attenuation measurements were performed using gamma spectrometer of NaI (Tl) detector. The utilized radiation sources comprised 137Cs and ⁶⁰Co radioactive elements with photo...
The report aims at improving knowledge of the interaction between poplar and heavy metals and at parsing the poplar ability to remove or render harmless such inorganic elements contained in residual slags of leatherindustries. Scions of Populus x euramericana, clone I-214, were grown outdoors, in pots, in inert soil, pruned for a single shoot and subjected to three treatments: non-amended (C), ...
During carbon steel manufacture, slag residues are generated to remove material impurities from liquid metal and thus control the quality of carbon steel. As the utilization of secondary metallurgical slags is not as efficient as those of primary slags, a comprehensive characterization of steel ladle slag was performed. Pseudo-total concentrations of a wide range of elements were determined dur...
Abstract The distributions of precious metals (gold, silver, platinum, and palladium) between copper matte silica-saturated FeO x -SiO 2 /FeO -Al O 3 -CaO slags were investigated at 1300 °C $$ P_{{{\text{SO}}_{ 2} }} P SO 2 = 0.5 atm. experiments ...
In this study, novel slags with a high basicity index were used to refine silicon melts carbon dioxide injection effectively remove Ti from metallurgical-grade silicon. Different compositions of the initial slag used, and samples obtained during refining. The results indicate that Ti-removal rate initially increased an increase in index, it decreased after exceeded 1.4. During refining, emulsif...
In this research, the influence of chemical composition of slags and the melting rate on the impurity of commercial grade iron in ESR processing has been investigated.The chemical composition and microstructure studies were evaluated, using spectrophotometer,OMand EDX analyses attached to SEM.The results show that ESR process has successfully reduced the amount and size of inclusions. In some c...
The increasing concentrations of metallic Al or Al2O3 in secondary copper resources like electronic wastes motivate research into the slag chemistry high-Al2O3 iron silicate slags for optimizing industrial smelting process. In this study, effect on phase equilibria FeOx-SiO2-Al2O3 system was experimentally investigated at 1200 °C and pO2 10?8.6 atm. high-temperature experiments were undertaken ...
