Different Types of Iron Ore - Mineral Processing & Metallurgy

Impurities in Iron Ores. 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.
