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 80100 feet high and about 25 feet in diameter (Figure 2) in which the roasted ore, coke ...
