In theory, any ore containing iron or iron compounds is called iron ore. However, in the industrial or commercial it not only contains iron composition but also has use value. It is difficult to determine whether the ore has commercial value, so it is difficult to make a unified iron ore standard. For example, the iron ore produced by the Europe has very poor quality, simply because they cannot find better ore, they call his ore as iron ore. In Australia there are large amount of high quality iron ore, so they think Europe iron ore has no commercial value. Then, the iron ore used in Europe has not been seen as iron ore in the Australia. Another example, the ore seen as poor ore with low iron content in the past can rich the iron composition by today’s technology. So these ores has become valuable iron ores. Thus, we conclude that the industrial iron ore standard can be changed for the regional supply and demand relationship, industrial technology and transportation conditions. In current standards, the average iron content in more than 25% of the ore can be called the valuable iron ore. The following is the description of three main types iron ore: Magnetite: it is a mineral with chemical formula Fe3O4, one of several iron oxides and a member of the spinal group. It is black or brownish-black with a metallic luster, has a Mohs hardness of 5–6 and a black streak. Hematite, also spelled as hematite, is the mineral form of iron (III) oxide (Fe2O3), one of several iron oxides. Hematite is a mineral, colored black to steel or silver-gray, brown to reddish brown, or red. It is mined as the main ore of iron. Limonite is an iron ore consisting of a mixture of hydrated iron (III) oxide-hydroxides in varying composition. Limonite is one of the two principle iron ores, the other being hematite, and has been mined for the production of iron since at least 2500 BCE Henan Hongxing Mining Machinery Co., LTD is specialized in the production of jaw crusher, ore beneficiation...
