Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in colour from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite (Fe 3O 4, 72.4% Fe), hematite (Fe 2O 3, 69.9% Fe), goethite (FeO(OH), 62.9% Fe), limonite (FeO(OH)·n(H2O), 55% Fe) or siderite (FeCO3, 48.2% Fe). Ores containing very high quantities of hematite or magnetite (greater than about 60% i
Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in colour from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite (Fe 3O 4, 72.4% Fe), hematite (Fe 2O 3, 69.9% Fe), goethite (FeO(OH), 62.9% Fe), limonite (FeO(OH)·n(H2O), 55% Fe) or siderite (FeCO3, 48.2% Fe). Ores containing very high quantities of hematite or magnetite (greater than about 60% iron) are known as "natural ore" or "direct shipping ore", meaning they can be fed directly into iron-making blast furnaces. Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel—98% of the mined iron ore is used to make steel. In 2011 the Financial Times has speculated that iron ore is "more integral to the global economy than any other commodity, except perhaps oil".Wikipedia · Text under CC-BY-SA license

During the last ten years great strides have been made, on the Mesabi range, in the practice of beneficiating low grade iron ore material. By beneficiation is meant all methods of removing impurities, and raising the iron content to a point where it can be sold in open market, the principal impurities being silica and moisture.
Iron ore is the primary raw material from which metallic iron is extracted to make steel. The rapid increase in crude steel production in the last decade has seen major expansions in world iron ore production from around 1 billion tonnes (Bt) in 2001 to over 2.9 Bt in 2012.
And this article will recommend you 10 types of iron ore processing equipment, and share you 4 tips to choose suitable machines and manufacturer, hoping you can get some ideas. Here are the 10 types of most popular iron ore beneficiation machines.
Iron Ore Industry. Most commercial grade iron ore bodies do not require beneficiation to produce a saleable product. Low grade iron ore bodies can be beneficiated using the DEC Flotation column and produce a saleable product at a low production cost per ton.
Magnetic separation of iron ores is one of the fastest-growing segments of the minerals beneficiation industry. The tonnage of taconite ores processed annually by magnetic separator, in a few years, can reach 100 million. Magnetic separation occupies an attractive position in the field of ore beneficiation.
