HEMATITE

HEMATITE

Specular hematite is the most common iron mineral in unaltered iron formation associated with chert and magnetite. In altered iron formation, red hematite and limonite are most common (Hotchkiss, 1919; Carr and Dutton, 1959). Botryoidal hematite is also found.

Hematite is also known as quot;natural orequot;. The name refers to the early years of mining, when certain hematite ores contained 66% iron and could be fed directly into blast furnaces. Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel. 98% of the mined iron ore is used to make steel.

C. Hematite Hematite is iron oxide (Fe2O3). Iron ore is a natural red, brown or black rock. Pure hematite has a density between 4.9 and 5.5g/cm3. However, the physical properties of rocks in which hematite is the main constituent may vary considerably and the density of hematite ores can range between 3.2 and 4.3g/cm3.

Hematite And Magnetite Iron Composition

Hematite And Magnetite Iron Composition

20191220Magnetite iron is in 2 and 3 oxidation states whereas in hematite it is only in 3 oxidation state. This is the key difference between magnetite and hematite. Moreover magnetite has higher iron content than hematite therefore its quality is higher. Apart from that in colours too there is a difference between magnetite and hematite.
