What is a Blast Furnace?
The main purpose of a blast furnace is to convert the iron ores, mined in the form of hematite or magnetite, to pig iron The blast furnace is in use after the iron ores have been converted into iron-rich pellets, and the coke and limestone prepared in the considerable amounts...

Blast Furnace Slag
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 ....
