The Making of Iron & Steel

5 · major steelmaking method involves the melting and refining of steel scrap in an Electric Arc Furnace. Pig iron and refined iron ore pellets (briquetted iron) can also be used, and because his t method is economic at lower volumes these operations are called mini mills. Plants that use Electric Arc Furnaces can be sited closer to the market.

Metal Profile: Iron Properties and Characteristics

Iron was likely originally discovered and extracted as a result of wood burning on top of iron-containing ores. The carbon within the wood would have reacted with the oxygen in the ore, leaving a soft, malleable iron metal. Iron smelting and the use of iron to make tools and weapons began in Mesopotamia (present-day Iraq) between 27 BC.

How Is Cast Iron Made? | Sciencing

The making of cast iron begins with a combination of raw materials. Iron is rarely found in its pure form. Only meteorites contain pure iron. The iron in use for centuries is found in the combination of iron and other elements. These combinations are known as iron oxides. Mining pulls most of the iron from iron …
