Smelting and electrolysis are both ways of extracting metals from ore. Metallurgy's purpose is to generate iron that can be used. Metallurgy uses a wide variety of ores, including coal (coal mining) and sandstone (sandstone mining) (sandstone mining). Metallurgy is the study of metals, namely their characteristics and manufacturing processes.
