How to extract iron from its ore the method three substances are needed to enable to extraction of iron from its ore.The combined mixture is called the charge iron ore, haematite often contains sand with iron oxide, fe2o3.Limestone calcium carbonate.Coke mainly carbon.The charge is placed a giant chimney called a blast furnace.
In the case of multiple processing options, cut-off grade is used to determine which process or destination the ore will be sent to, by using the following equation where u1 is the utility of sending ore to process 1, and u2 is the utility of sending ore to process 2.Utility is defined as the value economic or otherwise of selecting a process.
How do we extract iron from its mineral ores how do we convert it into steel the raw materials needed i.E.Limestone, coke, air and iron ore and the chemistry of the blast furnace are fully described.Why convert iron into steel how do you make steel the manufacture of steel alloys is further described.Scroll down for revision notes on extraction procedures and theory which should.
Iron ore is usually a mixture of iron and vast quantities of impurities such as sand and clay referred to as gangue.The iron found in iron ores are found in the form of iron oxides.As a result of these impurities, iron must be first separated from the gangue and then converted to pure iron.
This chapter introduces the principle of how low-grade iron ores are upgraded to high-quality iron ore concentrates by magnetic separation.Magnetite is the most magnetic of all the naturally occurring minerals on earth, so low-intensity magnetic separators are used to upgrade magnetite ores.
The annualized plant results demonstrated that an iron ore concentrate containing 68.4 fe could be produced using the flow sheet from run-of-mine ore containing 29.1 fe, at a mass yield to the iron concentrate of 34.8, an iron recovery of 81.7, and a tailings grade of 8.2 fe.
