2017-10-18 Blast furnace slag (BFS) is a by-product from iron production in blast furnaces, which are fed by a mixture of iron-ore, coke and limestone. In the process, the iron ore is reduced to iron while all remaining materials form the slag, which is tapped off as a molten liquid and cooled.

2021-2-1 GGBFS is a by-product of iron- and steel-production from the reduction of iron ore to pig iron in the blast furnace [ 3 ]. The liquid slag is rapidly cooled to form granules, which are then ground to a fineness similar to Portland clinker. In 2018, 15 Mt. GGBFS were produced worldwide [ 4 ].

2020-10-18 Blast furnace slag. Blast furnace slag is recovered by melting separation from blast furnaces that produce molten pig iron. It consists of non-ferrous components contained in the iron ore together with limestone as an auxiliary materials and ash from coke. Approximately 290 kg of slag is generated for each ton of pig iron.
