Iron Ore Smelting Process - Bright Hub Engineering

Iron Ore HowStuffWorks

Smelting involves heating up ore until the metal becomes spongy and the chemical compounds in the ore begin to break down. Most important, it releases oxygen from the iron ore, which makes up a high percentage of common iron ores. The most primitive facility used to smelt iron is a bloomery.

Smelting - Wikipedia

Of the seven metals known in antiquity, only gold occurs regularly in native form in the natural environment. The others – copper, lead, silver, tin, iron and mercury – occur primarily as minerals, though copper is occasionally found in its native state in commercially significant quantities. These minerals are primarily carbonates, sulfides, or oxides of the metal, mixed with other components such as silica and alumina. Roastingthe carbonate and sulfide minerals in air converts them to oxides. The oxides, in turn, are smel
