At the processing plant, the taconite is crushed into very small pieces by rock crushing machines. The crushers keep crushing the rock until it is the size of a marble. The rock is mixed with water and ground in rotating mills until it is as fine as powder.
The iron itself is usually found in the form of magnetite (Fe3O4), hematite (Fe2O3), goethite (FeO (OH)), limonite (FeO (OH).n (H2O)) or siderite (FeCO3). The process of mining consists of discovery of an iron ore deposit through extraction of iron ore and finally to returning the land to its natural state. It consists of several distinct steps.
Production Process of Iron Ore Generally, the processing of iron ore needs several processing stages, including crushing, grinding, ore beneficiation, concentrating, drying, etc. The equipments for iron ore beneficiation is consisted of Jaw Crusher, Ball Mill，Classifier, Magnetic Separator, Flotation Machine, Concentrator Machine and Dryer.
When the material exits the mill, the iron ore is classified using cyclones or vibrating screens that separate fine and large particles. The large particles are diverted back into the crusher and the fine particles will undergo a spiral gravity separation process. 5.
The best grades of ore contain more than 60% iron. Lower grade ores are reined in order to remove contaminants, often through a process of crushing, washing, and magnetic separation.
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.
Benches are made for the process of iron ore mining. Mechanized mining involves creation of benches that are used for the purpose of drilling, blasting, and finally

To efficiently process iron ore for high quality steel production, frequent ore grade monitoring, during all steps of downstream processing, is mandatory. Independent from the ironmaking method, the optimal use of fuels and energy during sintering, pelletizing and direct reduction of iron ore (DRI) needs to be applied to stay competitive and produce environmentally friendly.

An ironworks (or iron works) is an industrial plant for the production of steel from iron ores! Before the iron ores can be fed to the ironworks, they must first be mined (ore extraction) and specially processed for the blast furnace process (ore processing). These process
The process of mining consists of discovery of an iron ore deposit through extraction of iron ore and finally to returning the land to its natural state. It consists of several distinct steps. The first is discovery of the iron ore deposit which is carried out through prospecting or exploration to find and then define the extent, location and value of the ore body.

21/11/2014· Iron ore can be mined from all places in the world but to be commercially viable, the percentage of iron in this iron ore needs to be at least 20%. This is because lower iron content in the ore will render all the money and effort exerted in mining the ore from under the surface of the earth a big waste. This is why minerals near the surface of the earth and containing as a high percentage of
