2 Answers. Iron ore comes in several forms but is essentially various iron oxides mixed with silicates. The chemistry behind a bloomery furnace is that the burning charcoal creates both a high temperature and a carbon rich atmosphere inside the furnace in which oxygen is taken away from the iron to react with the carbon (reduction).
To be economically viable for mining, iron ore must contain at least 20% iron. Magnetite ore has the highest proportion of iron, at 65%. Haematite ore also has a high content of iron at 60%. All iron ore contains ferric oxide and it is from this that iron is extracted. Approximately two billion tonnes of iron ore are mined each year.
Uses of Hematite (Iron Ore) Hematite is the world''s most important ore of iron. Although magnetite contains a higher percentage of iron and is easier to process, hematite is the leading ore because it is more abundant and present in deposits in many parts of the world.
Metallurgic Processes. ... Metal ores are formed in the process of ore genesis, and they are extracted through mining. Extractive metallurgy is the practice of removing valuable metals from an ore and refining the extracted raw metals into a purer form. ... The HIsarna steelmaking process is a process of primary steelmaking in which iron ore is ...
Hematite is the most important iron ore. The iron content of the pure minerals is as follows: Ankerite is a carbonate of lime, magnesia, manganese, and iron. It is of valuable composition, carries only 14 or 15% of iron, and is used more for its lime and magnesia as a flux than for its iron-content.
Iron ore comes as a mixture of Ferric and Ferrous Oxide (forms of iron oxide). At the smelter it is mixed with coke and limestone. The coke is the reducing compound. The limestone or some other substance is the flux. Coke is made from heating coal to a high temperature. The coke becomes almost pure carbon.
Iron ore grinding machine. Grinding is a powdering or pulverizing process using the rock mechanical forces of impaction, compression, shearing and attrition. Main machines in ore grinding process are ore mill equipment. The most common iron ore grinding mills in mining are ball mill, Raymond mill and high pressure suspension mill.
To obtain iron from ironstone the ore is first roasted with coal. This process is called sintering. Sintering drives off impurities, such as water, carbon dioxide, sulphur dioxide and arsenic compounds. It leaves a sinter which is mainly granules of magnetite (an oxide of iron).
