Form of extractive metallurgy whose main purpose is to produce a metal from its ore

• A. Smelting
• B. Refining
• C. Casting
• D. Ore Processing

Answer: (A)

Smelting is the form of extractive metallurgy whose main purpose is to produce a metal from its ore by heating the ore with a reducing agent to drive the chemical reduction of metal oxides to metal. This step directly yields the metal, whereas refining afterward cleans impurities, and other stages like ore processing prepare or shape the material rather than produce metal from the ore itself. For example, copper or iron ores are smelted to extract metal, while refining removes remaining impurities and casting shapes the molten metal into useful forms.
