  • Granulated blast slag (GBS) - Mineral Products Association

    Granulated Blast furnace slag (GBS) is a light coloured 0/4mm glassy sand produced by the rapid quenching of molten blast furnace slag using large volumes of water. Production and Processing. GBS or Granulate as it is sometimes known is produced by rapidly cooling molten Blast furnace slag with water as the slag is tapped from the furnace.

  • Electric Arc Furnace Slag | ASA | Australasian (iron & steel) …

    Production and Processing. An Electric arc furnace (EAF) produces steel by the melting of recycled steel scrap, using heat generated by an arc, created by a large electric current Lime added (as flux) combine with silicates and oxides to form liquid slag. EAF slag has a lower density than steel and therefore floats on top of the molten steel.
