The geophysical techniques used in the search for iron ores, as in most geophysical mapping, are based upon the presence of measurable contrasts of physical properties between the ore minerals and the surrounding rocks. This oxygen immediately combined with the abundant dissolved iron to produce hematite or magnetite. Mining of iron ore worldwide is an extremely large industry and it is one of the most valuable commodities because of its myriad uses and the high demand for products like structural steel. It is highly malleable and ductile. The plentiful iron pyrite, FeS 2 is not an acceptable ore because sulphur is a deleterious impurity in iron, and expensive to remove in refining. Nickel, cobalt, gadolinium, terbium, and dysprosium are also ferromagnetic. It got its name because it looks just like gold to people who don’t know what real gold looks like! Great Western Iron Ore Properties Inc has 100 mining claims on 2000 acres in northeastern Arizona. Iron pyrite is one of the most common sulfide minerals in the world that’s more popularly known as Fool’s Gold. Meteorites are classified as iron, iron-stone, or stony according to the relative proportion of their iron and silicate-mineral content. The amount of carbon in cast iron is 2 – 4.5% of its weight. The “ore group” iron ore textural classification scheme (Table 2.7 and Figures 2.7 and 2.8) has been developed to link ore texture to downstream processing performance including lump/fines ratio, beneficiation, blast furnace lump physical and metallurgical properties, or fine ore sintering quality (Clout, 2002). The reason behind this is that iron, as mentioned before, contain atoms that are very compact and have very little, but regular, spaces in between them. Some of its most important properties are ductility, malleability and thermal conductivity. Cast iron, an alloy of iron (Fe) and carbon (C), has gained popularity in the market because of its low cost. It is smelted into iron ingots, which are used to make tools and armor. Principals of Iron Ore Iron ore is mined mainly from secondary enrichment of lined iron formations and channel. Its atomic number is 26. Iron ore fines are characterized on a physical basis by variations in particle size, shape, density, porosity, surface area, roughness, and wettability.
