Extraction of Metals Good Science

Carbon Reduction of Metals. Metals with an intermediate reactivity, such as iron and zinc, which form part of minerals, need to be chemically extracted from ore. This is done by a process called carbon reduction. Carbon reduction is a type of displacement (redox) reaction, where carbon is used to displace the metal from the mineral compound. The crushed ore is mixed with carbon and heated to

Types of iron ore. The major rock types mined for the production of metallic iron are massive hematite, pisolitic goethite/limonite, which provide a 'high grade' ore, and banded metasedimentary ironstone, magnetite rich metasomatite, to a much lesser degree, rocks rich in siderite, rocks rich in chamosite which provide a 'low grade' ore.

The iron ore, coke and limestone are crushed into small round pieces and mixed and put on a hopper which controls the input. The most common ores of iron are hematite Fe 2 O 3, and magnetite, Fe 3 O 4. These ores can extract iron by heating them with the carbon present in the coke. Heating coal in the absence of air produces coke.

How Is Iron Extracted From the Earth Reference

Iron ores in the form of hematite (ferrous oxide) and magnetite are removed from the earth through mining. The use of heavy mining equipment is necessary to dig out large pits in an area with a large deposit of iron ore however, because iron does not occur naturally, it is necessary to use a blast furnace to separate or refine iron from the other substances in the iron ore.

Impurities in Iron OresIron Ore FormationOrigin of Iron Ore BodiesMagnetiteLimoniteSideriteThere are certain impurities that lower the value of iron ores or may even make them valueless. Sulphur in the ore goes partly into the iron and steel and makes them brittle. While it is possible by roasting the ore and by other means to remove the sulphur, the presence of any considerable amount is objectionable. Phosphorus in steel makes it brittle. For steel making the limit for phosphorus is one hundredth of one per cent for ten per cent of iron in the ore this is the so called BessemerLive Chat

Iron Ore Mining TechniquesMetal ExtractionTypes of Iron Ores

Iron ores are rocks and mineral deposits from which clanging iron can be reasonably extracted. The ores are generally prosperous in iron oxides and fluctuate in color ranging from dark grey, bright yellow, deep purple, to even rusty red. The iron by its own is usually found in the structure of magnetite (Fe3O4), hematite (Fe2O3), goethite, limonite or siderite. Hematite is also identified as
