Iron Production

The production of iron from its ore involves an oxidation-reduction reaction carried out in a blast furnace Iron ore is usually a mixture of iron and vast quantities of impurities such as sand and clay referred to as gangue The iron found in iron ores are found in the form of iron oxides Get price

Why is iron extracted from haematite instead of iron pyrites?

Mar 12 2017The reason is pyrite is exothermic can cause hazard in mines It is more economical to extract iron from others minerals pyrite is geologically unstable and will turn into sulfurous minerals and viable ores so it is best left for future mines Pyrite is only suitable for making sulfuric acid or jewellary Get price
