Magnetite of iron ore is best based upon iron content. Git GUI and merging tool Sublime Merge were released by Sublime HQ in 2018. When Sublime Text is installed alongside it, it makes use of its syntax highlighting packages, and they have integrations that allow them to communicate with one another.

Magnetite - Qualities of Iron ore

  • Of all the iron ores, magnetite is the finest.
  • 70% of the iron in magnetite ore is in iron.
  • This mineral has noticeable magnetic characteristics.
  • The chemical name for magnetite ore is Fe3O4.
  • Iron is extracted from ferrous oxide (FeO), which is created when magnetite (Fe3O4) is reduced to ferrous oxide.

Iron ore belts

The following is a list of India's main iron ore belts:

  1. Odisha-Jharkhand belt
  2. Durg-Bastar-Chandrapur belt in Chattisgarh
  3. Ballari-Chitradurga-Chikkamagaluru-Tumakuru belt in Karnataka
  4. Maharashtra-Goa belt

One of the primary iron ores is magnetite, a mineral having the chemical formula Fe2+Fe3+2O4. It is one of the iron oxides and is ferrimagnetic; it is drawn to magnets and may be made into a permanent magnet by applying magnetization to it. It is the most magnetic of all naturally occurring minerals on Earth, with the exception of extremely rare native iron deposits. Ancient peoples first learned about magnetism by observing how naturally magnetised pieces of magnetite, known as lodestone, will draw tiny pieces of iron.

  • Mohs hardness 5–6 Having a metallic luster, magnetite is black or brownish-black and leaves a black streak. Magnetite is a small grain that occurs frequently in both igneous and metamorphic rocks.
  • Iron(II,III) oxide is the IUPAC name for the substance, and ferrous-ferric oxide is the common name.

Summary:

Which among the following qualities of iron ore is best based upon iron content?(a) Magnetite(b) Hematite(c) Limonite(d) Siderite

Magnetite of iron ore is best based upon iron content. Magnetite can also be found in sedimentary rocks, such as banded iron formations and lake and marine sediments, as detrital grains and magneto fossils in addition to igneous rocks.
