Extracting iron Iron and aluminium GCSE Chemistry

in a huge container called a blast furnace. Iron ores such as haematite contain iron(III) oxide, Fe 2 O 3.The oxygen must be removed from the iron(III) oxide in order to leave the iron behind.

GCSE CHEMISTRY Extraction of Iron Haematite

Extraction of Metals. Extraction of Iron.. Iron is extracted from its ore in the blast furnace.. The main iron ore is called haematite. Haematite is iron(III) oxide Fe 2 O 3. The iron ore contains impurities, mainly silica (silicon dioxide). Limestone (calcium carbonate) is added to the iron ore which reacts with the silica to form molten calcium silicate in the blast furnace.

Iron removal by physical chemical way Lenntech

The elimination of the ferrous iron, by physical-chemical way, is obtained by raising the water redox potential by oxidation thanks to oxygen of the air and this by simple ventilation. In the case of acid water, the treatment could be supplemented by a correction of the pH. Thus, the ferrous iron is oxidized in ferric iron, which precipitates in iron hydroxide, Fe(OH)
