- The difference between roasting and smelting is that roasting uses oxygen and smelting uses a reducing agent to extract metals from ores12. Roasting involves heating the ore in the presence of air to remove impurities, such as sulfur and arsenic1. Smelting involves heating the ore with a substance, such as carbon or hydrogen, that can react with the metal oxide and reduce it to the pure metal12.
