23.3: Metallurgy of Iron and Steel Chemistry LibreTexts

The first step in the metallurgy of iron is usually roasting the ore (heating the ore in air) to remove water, decomposing carbonates into oxides, and converting sulfides into oxides. The oxides are then reduced in a blast furnace that is 80–100 feet high and about 25 feet in diameter (Figure 23.3.2 23.3. 2) in which the roasted ore, coke
