what raw materials are used to make iron?
431334
The raw materials used to produce pig iron in a blast furnace are iron ore, coke, sinter, and limestone. Iron ores are mainly iron oxides and include magnetite, hematite, limonite, and many other rocks. The iron content of these ores ranges from 70% down to 20% or less.

Most cast irons have a chemical composition of 2.5–4.0% carbon, 1–3% silicon, and the remainder iron. Grey cast iron has less tensile strength and shock resistance than steel, but its compressive strength is comparable to low- and medium-carbon steel.

Iron is mostly obtained from minerals hematite and magnetite. In smaller degrees, it can also be obtained from the minerals taconite, limonite and siderite, according to Jefferson Lab.

Cast iron and cast steel are both mostly made from iron, and therefore can be nearly indistinguishable in appearance. However, they are distinguishable by their physical properties, such as cast iron being more vulnerable to corrosion.

Raw Materials Silicon metal is made from the reaction of silica (silicon dioxide, SiO2) and carbon materials like coke, coal and wood chips. Silica is typically received in the form of metallurgical grade gravel.

Iron ore pellets are spheres of typically 6–16 mm (0.24–0.63 in) to be used as raw material for blast furnaces. They typically contain 64–72% Fe and various additional material adjusting the chemical composition and the metallurgic properties of the pellets.

Raw Materials Today's modern furnace uses stainless steel, aluminized steel, aluminum, brass, copper, and fiberglass. Stainless steel is used in the heat exchangers for corrosion resistance. Aluminized steel is used to construct the frame, blowers, and burners.

Iron ore, coal and air are the main raw materials for iron and steelmaking but many other substances are used.

Oxygen, in turn, yields silicon and the other elements found in between sulfur and magnesium in the periodic table. These elements, in turn, produce the ones that are near iron on the periodic table -- cobalt, manganese and ruthenium.

Uses of iron It is used to manufacture steel and also used in civil engineering like reinforced concrete, girders etc. Iron is used to make alloy steels like carbon steels with additives such as nickel, chromium, vanadium, tungsten, and manganese.

Iron that comes from plants is in a different form, called non-heme iron. Most fortified foods and iron supplements use non-heme iron, but some foods use actual iron metal. ... Since iron metal is magnetic, you can use a magnet to see the bits of iron found in breakfast cereal.

Stainless steel metal is formed when the raw materials of nickel, iron ore, chromium, silicon, molybdenum, and others, are melted together. Stainless steel metal contains a variety of basic chemical elements that, when fused together, create a powerful alloy.

Physical and Chemical Properties Iron, like other metals, conducts heat and electricity, has a luster, and forms positive ions in its chemical reactions. Pure iron is fairly soft and can easily be shaped and formed when hot. Its color is silvery white. Iron is easily magnetized.
