Different Types of Iron Ore - Mineral Processing

Impurities in Iron OresIron Ore FormationOrigin of Iron Ore-BodiesMagnetiteLimoniteSideriteThere are certain impurities that lower the value of iron ores or may even make them valueless. Sulphur in the ore goes partly into the iron and steel and makes them brittle. While it is possible by roasting the ore and by other means to remove the sulphur, the presence of any considerable amount is objectionable. Phosphorus in steel makes it brittle. For steel-making the limit for phosphorus is one hundredth of one per cent for ten per cent of iron in the ore; this is the so-called Bessemer...

Hematite - Wikipedia

2020-6-7  Hematite, also spelled as haematite, is a common iron oxide with a formula of Fe 2 O 3 and is widespread in rocks and soils. Hematite forms in the shape of crystals through the rhombohedral lattice system, and it has the same crystal structure as ilmenite and corundum.Hematite and ilmenite form a complete solid solution at temperatures above 950 °C (1,740 °F).

Influence of Texture and Trace Element Composition

In contrast, Guelbs magnetite ore formed by reduction of a hematite Banded Iron Formation during metamorphism. As such, its trace element signature is similar to BIF hematite ores. In essence, Guelbs displays an inherited hematite composition, containing elements that are compatible, and would therefore have partitioned into the original hematite.
