  • Smelting - Wikipedia, the free encyclopedia

    This includes production of silver, iron, copper and other base metals from their ores. Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gasses or slag and leaving just the metal behind. Plants for the electrolytic reduction of aluminium are also generally referred to as aluminium smelters. These minerals are primarily carbonates, sulfides, or oxides of the metal, mixed with other components such as silica and alumina. Roasting
