Australia and Brazil are among the world’s largest iron ore producers and hold a large portion of the world’s iron ore reserves. Australia makes up half of the world’s iron ore exports. Brazil exported around 23 percent of the world’s total iron exports.

Magnetite is the finest iron ore with a very high content of iron up to 70 per cent. It has excellent magnetic qualities, especially valuable in the electrical industry. Hematite ore is the most important industrial iron ore in terms of the quantity used, but has a slightly lower iron content than magnetite.

Pure iron is a bright silvery-white metal which oxidizes (rusts) rapidly in moist air or in water containing dissolved oxygen. It is soft, malleable, and ductile, and is strongly magnetic (ferromagnetic). Pure iron has little use – some for analytical chemistry and some in medicine.

A: Most nails made today are made of steels of varying compositions. You may find old nails which are made of pure iron, however (or they may be made mostly of rust by now). Some nails are made of aluminum or copper or zinc or even plastic!

Answer. As,pure iron cannot retain its magnetism for long time so it cannot be used for making permanent magnet. Cobalt-steel or some alloys of iron such as ALNICO are used for making permanent magnet.

Here are 10 things you use every day that couldn’t exist without iron and steel:

• Vehicles – cars, trucks, SUVs, semis, RVs, buses, trains.
• Appliances – refrigerators, washing machines, clothes dryers, stoves, dishwasher.
• Utensils – forks, spoons, knives and more.
• Medical – surgical stainless steel, implantable devices.

Iron Price

Though it has been an essential part of Earth since the planet’s inception, humans did not begin producing iron into usable implements and products until about 2000 B.C. The historic period known as the Iron Age began in south-central Asia, replacing what had been the key metal, bronze.

All iron on Earth was produced by large stars that existed before our Sun formed: the iron was created during nuclear fusion and later released when the parent star(s) exploded, presumably supernova. Thus the inner solar system has a high abundance of iron.

Iron is made inside stars, specifically red super-giants. The elements form together inside a star during fusion. When the supernova occurs, the iron fragments are blasted into the space. This is how Iron came to Earth millions of years ago.

Iron-Rich Foods Heme iron is found in meat, fish and poultry. It is the form of iron that is most readily absorbed by your body. You absorb up to 30 percent of the heme iron that you consume. Eating meat generally boosts your iron levels far more than eating non-heme iron.

Here are 12 healthy foods that are high in iron.

Not only is it good for your health, it is also a rich source of iron. Apples are a suitable and delicious option when it comes to boosting hemoglobin levels. Apart from containing iron, Pomegranate is also rich in calcium, protein, fiber and several other vitamins and minerals.
