    • Ways to Separate Metal From Ore Sciencing

      The process of separating a metal from its ore is known as smelting. Smelting is widely practiced today and has a long history dating back to the Bronze Age, when ancient peoples first learned the technique. Smelting methods range from the basic to the high tech, and are applied to a variety of materials, including aluminum, iron and copper.
