    Iron also appears in the iron sulphur proteins which are essential to aerobic life. The enzyme aconitase occurs in the citric acid cycle that oxidizes carbon to CO 2 in mitochondria, rearranging the citrate to isocitrate at the beginning of the cycle so it can be further processed. The prosthetic group in aconitase is the iron sulphur group

    The study aimed at investigating the chemical composition and microstructure of raw iron ore from the deposits in Muko area (south western Uganda). The quality of this iron ore was evaluated to establish its suitability to serve as a raw material for iron production. Samples were taken from the six hills of Muko ore deposits and tests carried out to establish their composition and properties.

    Impurities in Iron OresIron Ore FormationOrigin of Iron Ore BodiesMagnetiteLimoniteSideriteThere 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 BessemerLive Chat
