Pig iron is produced through the smelting of iron ore in a blast furnace, while sponge iron is produced through the direct reduction of iron ore in a rotary kiln. Pig iron has a higher carbon content, making it brittle and heavy, while sponge iron has a lower carbon content, making it more ductile and lightweight.
