Beneficiation - Wikipedia

Iron beneficiation has been evident since as early as 800 BC 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
