Impurities In Iron Pyrite

Iron compounds iron occurs in small proportions as oxides, carbonates and sulphides.They are converted into fe2o3 at lower temperatures of calcination.At higher temperatures iron combines with lime and silicates and forms complex silicate compounds.Pyrite or iron sulphide is regarded to be highly undesirable.For hydraulic limes 2-5 per cent.
