slag from iron ore processing

Blast furnace slag iron ore processing plant in cement

Blast furnace slag (BFS) is a nonmetallic by product of the manufacture of pig iron in a blast furnace. Blast furnace slag consists primarily of silicates aluminosilicates and calcium-alumina-silicates.Blast furnace slag forms when slagging agents (e.g. iron ore coke ash and limestone) are added to the iron ore to remove impurities.
