· The per cent of iron in the ore as mined must be not less than 50%, if it is to be used without being first improved (beneficiated) by cobbing, washing, calcining, or magnetic concentration. Leaner ore is found in very large quantities; and in a favorable situation, it may be workable by some concentrating process.

Iron ore can be bought or gathered, but for the sake of demonstration, we gathered the ore ourselves. The best time to collect iron ore is in the winter because the ocean is more active. Active waves separate the black, magnetic sand from lighter silica sand. This magnetic sand is an iron ore called magnetite, which when combined with carbon ...

· Without it, iron would not be a magnetic metal. Different crystalline structures result in different iron properties. Iron is ferromagnetic in its bodycentred cubic (bcc) alphaFE structure. At the same time, it does not show magnetism in facecentred cubic (fcc) gammaFe structure. BetaFe structure, for example, displays paramagnetic tendencies.
