iron processing, use of a smelting process to turn the ore into a form from which products can be fashioned. Included in this article also is a discussion of the mining of iron and of its preparation for smelting. Iron (Fe) is a relatively dense metal with a silvery white appearance and distinctive magnetic properties.

After the processing of ores or wastes, two main refining technologies (extractive metallurgy) are used to recover value: pyrometallurgy and hydrometallurgy. Pyrometallurgy exploits the chemical reactions that take place between minerals in solid state or melted and gases during processing in a high-temperature furnace.
