In South Africa, the roots of the iron and steel industry date back to the fifth century CE [2], with the smelting of iron lumps in pit furnaces.

Smelting Reduction: Most Efficient Technologies for ...

 · Abstract. Smelting reduction processes have been developed in the past as an emerging alternative for hot metal production. What they have in common is that coal is directly used; thus, coke making can be avoided in comparison to the blast furnace. They have been developed to overcome the high energy and emissions levels intensive processes of ...

Iron History - Metal Casting Institute

Iron Bloomery – The most basic process used from the iron-age to medieval times. Charcoal, iron ore and air are combined to smelt an iron "bloom". The iron bloom is forged and worked to the final "Wrought Iron" shape. During the iron-age, bloomery furnaces rapidly replaced open charcoal fires as an effective way to forge.
