Why is iron extracted from haematite, instead of iron pyrites?

Mar 12, 2017· The 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.
