Iron and steel slag, also known as ferrous slag, is produced by adding limestone (or dolomite), lime and silica sand to blast furnaces and steel furnaces to strip impurities from iron ore, scrap and other ferrous feed materials and to lower the heat requirements of the iron- and steelmaking processes. Ferrous slag forms as a dominantly calcium silicate melt that floats on top of the molten ...

­The more advanced way to smelt iron is in a blast furnace. A blast furnace is charged with iron ore, charcoal or coke (coke is charcoal made from coal) and limestone (CaCO 3 ­). Huge quantities of air blast in at the bottom of the furnace, and the calcium in the limestone combines with the silicates to form slag.

Iron ore concentrate (magnetite or hematite or their mixtures) and noncoking coal mixed in pellets are processed for 10 min by a single-stage heat treatment in an RHF, yielding high-quality (96–97% Fe), slag-free iron nuggets. These nuggets are easier to handle than DRI or hot-briquetted iron and are processed in EAF or (after remelting) in BOF.
