Iron INTRODUCTION Iron, symbol Fe, magnetic, malleable, silvery white metallic element. The atomic number of iron is 26; iron is one of the transition elements of the periodic table (see Periodic Law).

CHEMICAL PROPERTIES

COMMON IRON ORES • HEMATITE,MOST ABUNDANT IRON ORE Fe2O3 • GOETHITE • SIDERITE • TECONITE • MAGNETITE Fe3O

Hematite Hematite, mineral and the most abundant ore of iron, composed of ferric oxide, Fe2O3. It is widely distributed over the world, occurring in rocks of all ages. Goethite Goethite, common ore of iron, and one of the most commonly occurring minerals in nature. An iron hydroxide mineral, FeO (OH), goethite generally contains about 63 percent iron.

Siderite Siderite, also chalybite, brown, translucent or transparent mineral with a glassy luster, composed essentially of iron carbonate, FeCO3.

Taconite Taconite, hard, flint like sedimentary rock of chemical origin, rich in particles of the red iron oxide, hematite, and the black iron oxide, magnetite.

Magnetite Magnetite, mineral and common ore of iron having the composition Fe3O4.

Red Cliffs, Hamersley Range The red cliffs of Australia’s Hamersley Range are a sign of the mountains’ rich iron deposits.

Drilling holes to a depth of about 15 meters that are then carefully loaded with explosives

Ore is unloaded in one of the 3 Loading Pockets and which is then fed into automatic trains

Removing silica from the ore.

Extracting iron from iron ore using a Blast Furnace Introduction The common ores of iron are both iron oxides, and these can be reduced to iron by heating them with carbon in the form of coke. Coke is produced by heating coal in the absence of air. Coke is cheap and provides both the reducing agent for the reaction and also the heat source.
