EAF slag is a rock-like material generated during the steel-making process. Approximately 130 facilities across the United States generate EAF slag. EAF slag is used as an alternative to rock fragments, both in encapsulated uses (e.g., contained in concrete) and unencapsulated uses (e.g., loose ground cover material).
A highly effective method of the processing of steelmaking dust in an arc-resistant furnace has been presented. The aim of the research was to investigate the possibility of processing steelmaking dust in terms of waste minimization and selective recovery of valuable components. For this purpose, an electric arc resistance furnace …
