Different Types of Iron Ore Mineral Processing amp; Metallurgy

• Impurities in Iron Ores
• Iron Ore Formation
• Origin of Iron Ore Bodies
• Magnetite
• Limonite
• Siderite
  There 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 BessemerOnline Service
