Hematite Physical - Optical Properties, Occurrence, Uses

Hematite is dense and hard, it is the most important ore of iron because of its high iron content and its abundance.The mineral occurs in various habits: steel-gray crystals and coarse-grained varieties with a brilliant metallic luster are known as specular hematite; thin, scaly forms make up micaceous hematite; and crystals in petal-like arrangements are called iron roses.

Determination of Iron in a Hematite Ore

The iron from hematite is reduced from Fe(III) to Fe(II) upon forming the halogenated iron complex. This reaction is described as follows: Sn 2+ + 2 Fe 3+---> 2 Fe 2+ + Sn 4+ (2) Excess Sn 2+ in solution is removed by adding mercuric chloride producing insoluble Hg 2 Cl 2:
