Pig Iron vs. Sponge Iron
Pig iron and sponge iron are both intermediate products in the iron and steel manufacturing process, but they differ in their composition and production methods. Pig iron is produced by smelting iron ore in a blast furnace, which results in a high carbon content (around 3-4%) and impurities such as sulfur and phosphorus.
