Solution. Different types of iron ore contains varying percentage of pure iron. Magnetite, haematite, limonite, siderite are the ores of Iron. Magnetite is the best quality of iron ore and contains 72% pure iron. Haematite contains 60% to 70% pure iron ore. Limonite contains 40% to 60% pure iron.

There is 40-60% pure iron in limonite. Siderite contains many impurities and has pure iron of just 40-50%. Ores containing very high haematite or magnetite amounts (greater than about 60 per cent iron) are referred to as "normal ore" or "direct shipping ore," which means that they can be fed directly into blast furnaces that produce iron.

A small amount of limonite exists along the edge of the pyrite. Moreover, some of these sulfide minerals could be observed. Limonite mainly exists in fine or tiny particle, with the particle size distribution ranging from 0.005 to 0.104 mm. Among them, symbiotic aggregation of magnetite and hematite is relatively coarse.

Pure magnetite contains 72.4 percent iron, hematite 69.9 percent, limonite 59.8 percent, and siderite 48.2 percent, but, since these minerals never occur alone, the metal content of real ores is lower.
