GCSE CHEMISTRY
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 silie in the blast furnace.
Raw materials
· For the extraction of metallic iron, the compounds formed between iron and oxygen, socalled oxides, play a wholly dominant role. The iron ore mineral is called magnetite (black ore) or hematite (bloodstone ore), depending on the type of oxide of which it is composed. Magnetite has acquired its name through its magnetic properties.
