Smelting is a process used to extract metal from its ore by heating it to high temperatures. During this process, the ore is combined with a reducing agent, often carbon, which helps to separate the metal from other elements in the ore. The result is a purified metal that can be further processed or shaped into various products. This technique is commonly used for metals like iron, copper, and lead. Smelting plays a crucial role in the metal industry, as it allows for the production of metals that are essential for construction, manufacturing, and various technologies.
