Extraction of iron from hematite
Understand the Problem
The text provides detailed information on the extraction of iron from hematite using a blast furnace, including the reactions that occur in different zones of the furnace and the purpose of each raw material.
Answer
Iron is extracted from hematite in a blast furnace using coke and limestone.
The extraction of iron from hematite involves processing in a blast furnace, where hematite reacts with coke and limestone, yielding iron and carbon dioxide.

More Information
Hematite (Fe2O3) is primarily used for extracting iron, which is then further processed to reduce impurities. This iron, known as pig iron, contains about 4% carbon along with other impurities.
Tips
A common mistake is not distinguishing between chemical formulas for the compounds involved, such as mistaking Fe2O3 for pure iron.
