Why is Limestone added to a Blast Furnace for producing Iron?
it purifies it
Would rust damage limestone?
Rust is characteristic for iron and alloys (metals), not for a salt as limestone.
Why is limestone added to the blast furnace during the extraction of iron?
Iron ore contains the impurities sand and clay, which are silicon oxides. Limestone is added to remove these impurities.
What is the process of smelting iron ore?
Iron ore is not normally smelted, instead it is reduced in a blast furnace with a mixture of coke & limestone. The coke burns removing the oxygen from the iron ore and melting the resulting iron. The limestone neutralizes acidic sulfur compounds and acts as a flux.
