However, while it looks very simple and straightforward, in fact to be accurate we have to take into account several factors.The most obvious one concerns all permanganate titrations when permanganate is used as a titrant we should use different technique to read volume of liquid in the burette. The meniscus is not visible, as the solution is opaque thus we have to look at the top of the liquid.As Fe2+ ge

    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-call
