found as native metal so therefore carbon can be used to reduce it (note: reduction can also mean to remove the oxygen from a compound). This is done in a blast furnace. The most common ore of iron is called haematite (iron(iii) oxide). Its formula is Fe 2 O 3.and solid to liquid ratio had significant effects on the leaching process. The highest iron extraction of 97.7% was obtained at 140 °C,
