  • Slag Wikipedia

    Slag is the glass-like by-product left over after a desired metal has been separated (i.e., smelted) from its raw ore.Slag is usually a mixture of metal oxides and silicon dioxide.However, slags can contain metal sulfides and elemental metals. While slags are generally used to remove waste in metal smelting, they can also serve other purposes, such as assisting in the temperature control of

  • Steelmaking Process an overview | ScienceDirect Topics

    Since scrap metal is used instead of molten iron, no coke making or iron making operations are associated with steel production using an EAF. This technology results in the production of metal dusts, slag, and gaseous products. Particulate matter and gases evolve together during the steelmaking process and are conveyed into a gas cleaning system.
