Which among the following qualities of iron ore is best based upon iron content? ›

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.

Magnetite is the finest ore among all the ores of Iron. Magnetite ore comprises seventy per cent of iron. The magnetic properties in this ore are appreciable.

Solution: Magnetite is the best variety of iron ore. Iron ore is the basic mineral and backbone of industrial development. India has abundant sources of iron ore.

Haematite is the main ore for present iron smelting.

The iron ores were classi- fied into hard massive, flaky-friable, blue dust and lateritic ores (Table 1). The hard massive ores are grey in colour and lumpy in nature and are partly laminated. Bulk density of these ores varies between 2.1 and 2.9 and the specific gravity ranges from 3.4 to 4.7.

One can find four types of iron ores on earth. They are Haematite, Magnetite, Limonite and Siderite. Haematite has the highest percentage of metallic iron in it. Magnetite comes next in metallic iron content.

Complete answer: Hematite and magnetite are the best quality and most significant iron ores for steelmaking. Hematite is the most sought-after ore and the preferred raw material in productive steel mills.

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.

Pure magnetite contains 72.4 percent iron, hematite 69.9 percent, limonite 59.8 percent, and siderite 48.2 percent, but, since these minerals never occur alone, the metal content of real ores is lower.

The most common ore of iron is hematite. It has the formula Fe 2 O 3 .

How do you identify iron ore? ›

Iron ores have variable appearances. Hematite, for instance, can range from coarse to metallic. Its colour also fluctuates from red and brown tones to black, dark grey, or silver tones. However, when scraped across a scrape plate, all hematite specimens will produce a reddish streak.

In the Earth's crust iron is found mainly as minerals of iron oxide such as hematite, magnetite, goethite and limonite. The minerals that are mostly used as ore for making iron are hematite (Fe₂O₃) and magnetite (Fe₃O₄).

Magnetite, Haematite, Siderite and Limonite are the four types of iron ores found in India.

The iron is usually found in the form of magnetite which has 72.4% iron, hematite with 69.9% iron, goethite with 62.9% iron, limonite or siderite with 48.2% iron.

The correct answer will be Siderite (10-40%), Limonite (35-50%), Magnetite (60-65%), Haematite (60-70%). Iron Ore is classified into Haematite, Magnetite, Limonite & Siderite.

There are four main types of iron ore deposit: massive hematite, which is the most commonly mined, magnetite, titanomagnetite, and pisolitic ironstone. These ores vary in colour from dark grey, through to deep purple, rusty red and bright yellow.
