Iron formation consists of iron ore such as siderite, magnetite, and hematite, with silica in the form of chert, jasper, etc., generally in bands, but sometimes not distinctly so. The bands of iron ore are at times highgrade, but are often mixed with a good deal of silica, the whole making an ore too lean for use without concentration.
Hematite: A primary ore of iron and a pigment mineral. Uses of Hematite (Iron Ore) Hematite is the world's most important ore of iron. Although magnetite contains a higher percentage of iron and is easier to process, hematite is the leading ore because it is more abundant and present in .
Magnetite ore has the highest proportion of iron, at 65%. Haematite ore also has a high content of iron at 60%. All iron ore contains ferric oxide and it is from this that iron is extracted.
Jul 28, 2017· Hematite, the most desirable iron ore because of its high iron content, is found throughout the world, with its highest abundance being seen in Australia, Brazil, and parts of Asia. Since the 1960's, highgrade hematite ore has served as the major source of iron mined in Australia.
