The archaeology and technology of metal production in the Late Iron Age of the Southern Waterberg, Limpopo Province, South Africa [PDF]

, 2013
Includes abstract.The inception of metallurgy in southern Africa was relatively late, compared to other regions in Africa, and as a result, this part of the sub-continent was mistakenly thought to have been less innovative during the Iron Age.

Modification of Copper Slag Using Steel Slag and Magnesium Slag Additives

Metals
Significant amounts of smelting slag are generated during the production of steel, refined copper, and refined magnesium. These slags contain abundant valuable metallic elements, such as Fe, Cu, Zn, Co, and Mg, that have not been fully utilized in the past.

Slags

, 2012
Selective extraction of valuable elements (such as V, Cr, Mn, etc.) and their compounds from metallurgical slag is in a focus of many researchers. Although vanadium may be present in slag as oxides and/or complex spinels with Fe, Mn, etc.

Differences in morphological properties between the olivine group minerals formed in natural and industrial processes [PDF]

Journal of Mining and Metallurgy. Section B: Metallurgy, 2007
Olivines are a large isomorphic series of minerals, belonging to silicates group. Regardless of their chemical composition, any of these minerals can be formed both in natural and industrial processes.

Dissolution behavior of AlN in CaO–Al2O3–BaO–CaF2–Li2O system mold fluxes

Journal of Materials Research and Technology, 2023
The dissolution behavior of AlN in three CaO–Al2O3–BaO–CaF2–Li2O non-reactive mold fluxes which were designated as N1 (low break temperature), N2 (good lubrication performance), N3 (high break temperature) for high-Al steel with different requirements ...

Slags

, 2014
Thermodynamic data with regard to slags containing vanadium oxide are scarce and scattered. In the present study, the classic gas-slag equilibrium technique has been adopted to investigate the phase relationships in the CaO-SiO2-MgO-Al2O3-V2O3 slags. The

Utilization of Slags from Foundry Process [PDF]

, 2017
The melting of steel or cast iron is one step of the foundry process. The foundry industry uses different types of furnaces, and metallurgical slags are products of the pyrometallurgical processes defecting in these furnaces.

Influence of Slag Composition on Slag–Iron Interfacial Tension

ISIJ International, 2006
Interfacial tensions between liquid iron and slag were examined for CaO–SiO2 binary and CaO–SiO2–Al2O3 ternary slag systems. The influences of FeO, MgO, B2O3, TiO2, BaO and ZrO2 in slag on the interfacial tension were also investigated by varying these oxides from 1–30 wt% in the CaO–SiO2 binary or CaO–SiO2–Al2O3 ternary slag systems.The interfacial ...
