Iron (Fe) accounts for the highest-content of valuable metal recoverable from copper slag, which is most effectively recycled using pyrometallurgical high-temperature treatment. It is believed that the roasting temperature significantly affects the p

The study aims experimentally investigate how to obtain a ferrosilicon alloy using iron silicate - fayalite generated after flotation enrichment of slag in pyrometallurgical production of copper. This material contains about 46 % iron and about 27 %

Because of its high cement consumption, which limits its use in concrete construction, self-compacting concrete requires a higher cement content and various admixtures. Therefore, it is prudent to explore alternative options to minimize environmental

In general, phosphate cements have a very rapid setting reaction at room temperature. The same holds for copper slag-based phosphate cements. This means that using them as a binder, for instance as mortar, is always possible on a small scale, but ver

A stabilized zirconia oxygen probe was used to measure the oxygen partial pressure (OPP) at an electrode submerged in a copper slag melt at 1300 ℃. The OPP was controlled in the range of 10−10–10−5 atm owing to the presence or absence of a po

Abstract Fayalite slag (FS) is an Fe‐rich nonferrous metallurgy (CaO‐MgO‐) FeOx‐SiO2 slag originating from nickel or copper manufacturing processes, which currently is disposed to landfills or used in low‐value applications. This study inve
