Evolution of Ironmaking Techniques | From Ancient to …
As societies progressed, humans began to extract iron from terrestrial sources, marking the transition from the use of meteoric iron to smelting iron ore. One of the earliest known methods of iron smelting was the bloomery process. This ancient technique, dating as far back as 1200 BCE, involved heating iron ore in a furnace with charcoal.

From Ore to Iron with Smelting and Direct Iron Reduction
In the smelting reduction process, pelletized iron oxide ore or fine ore powders are pre-reduced in a fluidized bed or reduction shaft. The reduced iron along with coal and lime is fed to a gasifier-melter, which completes the reduction process and produces pig iron or hot metal of the same quality as a blast furnace. The reducing gases ...
