Granulated Blast Furnace Slag (GBFS) is a valuable by-product of steel manufacturing. Iron is extracted from iron ore, which takes place in a blast furnace where the ore, limestone or dolomite, and fuel (coke) are introduced into a furnace to assist the separation of the molten iron from the impurities. When taken out of the blast furnace, slag ...

The slag in iron production in a blast furnace operates at temperatures of about 1500 °C (Fig. 2) [55]. The blast furnace is fed with a cautiously regulated composition of limestone, coke and iron ore [1]. Iron is formed due to iron ore reduction and the remaining material becomes a slag that floats on the molten iron's top surface [49].
