Extraction of Iron from Haematite. 12. Refer to TB/244246 · The iron that is extracted from the blast furnace is known as cast iron, and is mainly used to produce steel. Steel. 13. · Steel is an alloy of iron with carbon and/or other metals.
Dec 09, 2020 · Ans. Ores which are magnetic in nature can be separated from the nonmagnetic gangue particles by magnetic separation. For example, ores of iron such as haematite (haematite (Fe2O3), magnetite ( FeCO3) and iron pyrites(FeS3) being magnetic can be separated from nonmagnetic silica and other impurities by magnetic separation method.

Iron, when extracted from iron ore such as haematite containing iron (III) oxide, Fe2O3, in a blast furnace is called iron extraction blast furnace metallurgy. In this reduction reaction, oxygen is removed from the iron (III) oxide to leave behind iron. Generally, the extraction of metals and their isolation are based on three major procedures.
Iron is extracted by chemical reduction from the ores haematite (Fe 2 O 3), magnetite or Iron (III) carbonate (FeCO 3) . Occurrence: Iron does not occur free in occurs combined with other elements as ores. It is the second most abundant metal found in the earth's crust after aluminium.
charcoal, graphite), in a a process called smelting. (4) The metal iron can be obtained in this way in a blast furnace (picture above). (5) The metals which are easiest to extract have been used for thousands of years, but metals like aluminium were not extracted until recently when more advanced technology was invented and the reactivity of a metal explains some of its uses.
The pig iron is then converted to wrought iron or steel according to the requirement. Smelting is carried out in a furnace, it is almost cylindrical furnace, lined with fire bricks. Iron ore (haematite Fe 2 O 3) is calcined to remove volatile impurities like sulphur and arsenic. The calcined ore (8 parts) along with limestone (1 part) and ...
