Blast Furnace Slag - Material Description - User,

In the production of iron, iron ore, iron scrap, and fluxes (limestone and/or dolomite) are charged into a blast furnace along with coke for fuel. The coke is combusted to produce carbon monoxide, which reduces the iron ore to a molten iron product. This molten iron product can be cast into iron,Iron Ore Smelting Process - Brighthub Engineering,Large scale iron ore smelting has been carried out in numerous types of blast furnaces since the industrial revolution, with the basic ingredients of coke, iron ore and limestone remaining unchanged, being loaded into the blast furnace from where the molten iron is tapped into molds.In a blast furnace why are the coke and limestone needed?,the Coke supplies carbon monoxide to reduce the ore in a blast furnace and supplies heat to melt the iron.
