Abstract (en)
[origin: WO2022190147A1] Described is a process for obtaining mineral wools and, in particular, rock wool products starting from metallurgical slag deriving from an electric arc furnace (EAF) or from a converter. The process comprises adding EAF slag or converter slag ground and screened with soda carbonate (Na2CO3) to the mixture normally used in the production of mineral wools.
