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 color from dark grey, bright yellow, deep purple, to rusty red.
According to the various sources of iron as well as certain economic and safety aspects in regards to its extraction is included, we provide you with a suitable iron ore mining equipment. The course we provide information of Iron ore processing includes comprehensive information on the beneficiation of iron ore including comminution, sintering, upgrading, and pelletizing aspects.
The iron ore is distributed in Algeria,Egypt,Ghana,Kenya,Nigeria,South Africa,Sudan,Zambia,Zimbabwe,China,Russia,Australia,New Zealand,France,Germany,Iceland,Italy,Luxembourg,Netherlands,Norway,Spain,Sweden,Switzerland,Ukraine,United Kingdom,Canada,Cuba,Mexico,United States,Brazil,Chile,Peru,Venezuela,
Iron ores are typically used for the production of iron. Then the iron produced is to make steel. Steel is used to make automobiles, locomotives, ships, beams used in buildings, furniture, paper clips, tools, reinforcing rods for concrete, bicycles, and thousands of other items. It is the most-used metal by both tonnage and purpose.
Mining and processing of iron ore involves coarse crushing and screening. Iron ore is beneficiated by crushing and then separating the iron from the gangue minerals through screening. This is usually so efficient that lower grade ore can be treated especially when the magnetite is quite coarse. Common iron ore crushers are jaw crusher, cone crusher and fine jaw crusher.
You will obtain three kind of iron ore particles after screening, respectively of 75~12mm, 12~2mm, 2~0mm in size. The largest ore particles pass to dry magnetic separation with shaking chute, the middle ones are moved to dry magnetic separator with coarse jigging, and the smallest to wet magnetic separator with fine jigging. The middlings produced by three processes are moved to screening process. The tailings of wet magnetic separation will be discharged directly.
After the second crushing machine, iron ore particles are moved to secondary crushing and the first ball mill grinding. With fine ore particles, it is more efficient to upgrade iron ore. Wet ball mill and fine ore crushers are used during this process.
The obtained iron ore mines materials are moved to flotation desulfurization process, then to weak magnetic separation. The obtained product is iron ore concentrate. And low iron content material is discharged as tailings. You will also obtain sulphide concentrate as by-product through flotation desulfurization.

In the United States, almost all of the iron ore that is mined is used for making steel. The same is true throughout the world. Raw iron by itself is not as strong and hard as needed for construction and other purposes. So, the raw iron is alloyed with a variety of elements (such as tungsten, manganese, nickel, vanadium, chromium) to strengthen and harden it, making useful steel for construction, automobiles, and other forms of transportation such as trucks, trains and train tracks.
While the other uses for iron ore and iron are only a very small amount of the consumption, they provide excellent examples of the ingenuity and the multitude of uses that man can create from our natural resources.
Powdered iron: used in metallurgy products, magnets, high-frequency cores, auto parts, catalyst. Radioactive iron (iron 59): in medicine, tracer element in biochemical and metallurgical research. Iron blue: in paints, printing inks, plastics, cosmetics (eye shadow), artist colors, laundry blue, paper dyeing, fertilizer ingredient, baked enamel finishes for autos and appliances, industrial finishes. Black iron oxide: as pigment, in polishing compounds, metallurgy, medicine, magnetic inks, in ferrites for electronics industry.
In accordance with the characteristics of mineral composition, structure, construction and mining, sorting, Metallurgical and process iron ore is divided into two major categories of the type of natural and industrial type.
1) According to the iron-bearing mineral species can be divided into: magnetite ore, hematite iron ore, the illusion, or semi martite iron ore, vanadium-titanium magnetite ore, limonite, siderite iron ore as well as by one of two or iron mineral composition of two or more kinds of mixed ore.
2) Press the harmful impurities (S, P, Cu, Pb, Zn, V, Ti, Co, Ni, Sn, F, As) content of the high and low, can be divided into high-sulfur iron ore, iron ore of low sulfur, high phosphorus iron ore, low phosphorus iron ore.
3) According to the structure, the structure can be divided into disseminated ore stockwork disseminated ores, striped ore, banded ore, the dense massive ore, brecciated ore and oolitic, bean-shaped, kidney-shaped honeycomb , powder, earthy ore.
Most useful metal in the world, Iron, is extracted from iron ore. It is the rock from which metallic iron can be economically extracted. Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). The iron ore, usually, very rich in iron oxides (Fe3O4 and Fe2O3). Iron ores are mostly dark grey to rusty red in color and high specific gravity.
Raw Iron Ore Crushing Process:Large raw iron ore are fed to the jaw crusher evenly and gradually by vibrating feeder through a hopper for primary crushing. After first crush, the material will transferred to cone crusher by belt conveyor for secondary crush; the crushed iron ore stone will then transferred to vibrating screen for separating. After separating, the parts that can meet standard will be transferred away as final products, while the other parts will be returned to cone crusher, thus forming a closed circuit. Size of final products can be combined and graded according to your specific requirement.
Iron is found in the world's oldest and most widely used, is the largest amount metal, the metal consumption of about 95% of total consumption.Iron ore is mainly used for iron and steel industry, smelting iron and steel according tothe different carbon content.The so-called iron ore deposits is the main target of industrial development and utilization.Iron ore beneficiation plant is generally divided into several stages, crushing, grinding, classification and separating. The current iron ores beneficiation plant generally through the crusher crushed the raw ore, and then into the ball mill smashed through the gravity separation, flotation , extracted from the concentrate and tailings, and through chemical methods, and iron ore beneficiation products eventually become finished products.
Raw iron ores are crushed by jaw crusher, then get a reasonable degree of fineness iron ore. These relatively small iron ore particles enter ball mill for grinding through the elevator and vibrating feeder. After ball mill grinding, the milled ore gets the next procedure: classification. Because of different proportion of solid particles in the liquid precipitation at different speeds of the principle, spiral classifier clean and grade the iron ore mixture. When the iron ore mixture which has been cleaned and classified get through magnetic separator, the magnetic material of iron ore mixture will be separated by magnetic and mechanical force. Then these iron ore particles are into flotation separator. Depending on the mineral characteristics with different drugs, making the iron ore and other substances to be separated. These semi-finished products should be dried by dryer then the iron come into being.
