Iron beneficiation has been evident since as early as 800 BCE in China with the use of bloomery . A bloomery is the original form of smelting and allowed people to make fires hot enough to melt oxides into a liquid that separates from the iron. Although the bloomery was promptly phased out by the invention of the blast furnace, it was still heavily relied on in Africa and Europe until the early part of the second millennium. The blast furnace was the next step in smelting iron which produced pig iron. The first blast f

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. Magnetite is magnetic, and hence easily separated from the gangue minerals and capable of producing a high-grade concentrate with very low levels of impurities.
