The production and trade of metals was the foundation economic wealth many regions in world, which makes study ancient metallurgical slags primary importance. This type is relatively new for Bulgaria, where research field started late 1960s with chemical analysis copper ore, slags, tools finished goods from mine Ay-bunar area. Iron one most commonly found elements earth’s crust its deposits are...

K. Nowińska, Silesian University of Technology, Faculty of Mining and Geology Z. Adamczyk, Silesian University of Technology, Faculty of Mining and Geology E. Melaniuk-Wolny, Silesian University of Technology, Faculty of Energy and Environmental Engineering, Gliwice, Poland Complex analysis of concentration and form of occurrence such metals as Zn, Pb, Fe and Cu in slags formed during a current...

With the continuous urbanization and industrialization in the world, energy saving and greenhouse gas (GHG) emission reduction have been serious issues to be addressed, for which heat recovery from traditional energy-intensive industries makes up a significant strategy. Here we report a novel approach to extract the waste heat and iron from high temperature steel slags (1450-1650 (o)C) produced...

Recent excavations made by University of Lecce in Piazzetta Epulione and Piazza Castromediano (Lecce) have produced structures and artifacts related to metal-working. Most of the evidence dates back to the Roman period; traces of metallurgical activity can also be traced to the periods preceding and following the Roman period. Iron slags and semi-finished objects have been found in Piazzetta Ep...

TiN and Ti2O3 are the predominant inclusion types in Ti-alloyed ferritic chromium stainless steels. In order to ensure the required steel cleanness level, an effective removal of such inclusions in the slag during secondary metallurgy is essential. This inclusion removal predominantly takes place via dissolution of the inclusion in the slag. The dissolution behavior of TiN and Ti2O3 in CaO-SiO2...

To determine slag properties and the factors influencing these for optimization of operating conditions in copper flash smelting process, composition microstructures quenched converting slags have been analyzed. Thermodynamic software FactSage 8.2 has used to investigate effects matte grade, SO2 partial pressure, Fe/SiO2 ratio on liquidus temperature content slag. The possibility recover valuab...
