The primary mineral would be... hematite. Many other minerals could be present, to one degree or another, including magnetite, pyrite, quartz, etc.
Examples of iron minerals: magnetite, hematite, goethite, siderite, limonite etc.
The density of iron ore is variable. Iron ore refers to a rocktype that contains iron minerals. The type and concentration of the iron minerals as well the type and concentration of non-iron minerals determines the density of the iron ore. Typical high grade iron ore is approximately 65% hematite and 35% other (commonly silicate). The density of hematite is approximately 5 g/cc and a general density for crustal rocks (silicates) is approximately 2.67 g/cc. Therefore iron ore that is 65% hematite and 35% silicate would have a density of approximately 4 g/cc.
Hematite is an ore of the element Iron.
Magnetite belongs to the spinel group of minerals
Hematite is an ore of iron.
The term "iron ore" is quite general, and can be applied to a number of different minerals, like hematite, magnetite, goethite, or pyrite.
The principal ore for iron is haematite.
There are a variety of iron ores such as the minerals limonite, hematite, magnetite, that are rich in the element iron and mined extensively for the production of iron and steel.. These minerals, in addition to iron, contain other elements.
An ore is a rock that contains minerals that are useful. For an ore to be considered an ore reserve, it must be economically viable (the value of the extracted mineral must exceed the cost of extraction and processing) and must be technically and legally possible to extract.
Hematite is a mineral. This is from wikipedia: A mineral is a naturally occurring solid with a definite chemical composition and a specific crystalline structure. A rock is an aggregate of one or more minerals. Have a look at this page in wiki about hematite: http://en.wikipedia.org/wiki/Haematite
it is found in iron ore eg hematite
Hematite and Magnetite are the main ores of Iron.
