Lower-grade sources of iron ore generally require beneficiation, using techniques like crushing, milling, gravity or heavy media separation, screening, and silica froth flotation to improve the concentration of the ore and remove impurities. The results, high-quality fine ore powders, are known as fines.
Iron wasn't invented. It is an ore and comes from iron mines. Steel is made from iron using a process of heating the ore and then removing the impurities from the ore through blowing air through.
In steelmaking, impurities such as nitrogen, silicon, phosphorus, sulfur and excess carbon (most important impurity) are removed from the sourced iron, and alloying elements such as manganese, nickel, chromium, carbon and vanadium are added to produce different grades of steel.

Flake Hammerscale is produced in large quantities during multiple stages of the smithing process. To create the pure iron necessary for forging, a smith must first purify the iron ore. The smelting of ore creates a ‘bloom’, a porous mixture of slag and metal. The smith then repeatedly heats and hammers the bloom to remove impurities.

The Corex process consists of two main parts a Reduction Shaft and a Melter- Gasifier. The main reagents for the Corex process are iron ore, noncoking coal, and oxygen. Unlike the Blast furnace the Corex process does not use a hot blast of nitrogen, thereby greatly reducing NOx gas emissions, but instead uses oxygen.

Iron ore minerals, particularly hematite and goethite, are beneficiated by a combination of size fraction, preconcentration, and flotation in stages (Fig. 13.45).Iron ore requires removal of silicate impurities of a finer size by flotation for higher-grade products of +60% Fe. ROM ore at 400–600 mm is fed to a primary crusher with product set at –40 mm.
The first stage is the removal of iron as a solid residue in the form of either jarosite (a basic ferric sulfate) or the oxides goethite or hematite. This is then followed by cementation with zinc dust to remove other metallic impurities (including copper, nickel, cadmium, cobalt, and germanium) from the solution.
