How is Iron Refined from Ore? (with pictures)

Apr 29, 2020 Although iron does not occur in its pure form in nature, some kinds of ore contain up to 70% iron atoms. Iron ore consists of oxygen and iron atoms bonded together into molecules. To create pure iron, one must deoxygenate the ore, leaving only iron atoms behind, which is the essence of the refining process. In its natural form, iron ore has aget price

Refining (metallurgy) Wikipedia

The product of the blast furnace is pig iron, which contains 4–5% carbon and usually some silicon.To produce a forgeable product a further process was needed, usually described as fining, rather than refining.From the 16th century, this was undertaken in a finery forge.At the end of the 18th century, this began to be replaced by puddling (in a puddling furnace), which was in turn graduallyget price

Iron (Element): Production and Refining Infoplease

Gray iron is brittle but soft and easily machined. White cast iron, or white iron, which is harder and more brittle, is made by cooling the molten iron rapidly. The carbon remains distributed throughout the iron as cementite (iron carbide, Fe 3 C). A malleable cast iron can be made by annealing white iron castings in a special furnace.get price
