Step 4: Carbon monoxide is a powerful reducing agent. This carbon monoxide reduces the iron (III)oxide to iron metal. Fe 2 O 3 (s) + 3CO (g) → 2Fe (l) + 3CO 2 (g) But in some places of the blast furnace, the temperatures are very high. In those high-temperature regions, carbon directly reduces the ore to iron.
Used for oxides of metals less reactive than carbon – the carbon displaces the metal, stealing the oxygen to form carbon dioxide and leaving the metal. Carbon is used because it is cheap and plentiful. 2) ELECTROLYSIS Can be used for any ore, but uses huge amounts of energy, so an expensive process. Therefore usually only used for metals more ...
Extraction and Uses of Metals. Metals are extracted from their ores using a method dependent on the position of the metal in the reactivity series. More reactive metals are extracted using electrolysis while less reactive metals can be heated with carbon. Other elements can be mixed with metals to produce alloys with different properties.
Metals occur in nature in free as well as combined form. Metals having low reactivity show little affinity for air, moisture, carbon dioxide or other non-metals present in nature. Such metals may remain in elemental or native (free) state in nature. Such metals are called "noble metals" as they show the least chemical reactivity.
Metals with an intermediate reactivity, such as iron and zinc, are chemically extracted from minerals by a process known as carbon reduction. Carbon reduction is a type of redox reaction, where carbon is used to displace a metal from a compound. The crushed ore is mixed with carbon and limestone, then heated to a molten state (smelted) in a ...

What is an ore? rock containing compound(s) from which metal can be extracted for profit b) Why does carbon displace lead in step 2? carbon is more reactive than lead c) Explain why the lead(II) oxide is reduced in step 2. loses oxygen
The carbon forms carbon monoxide which escapes from the iron as a gas. Phosphorus and silicon react with the oxygen to make acidic oxides which react with the basic calcium oxide to make compounds such as calcium phosphate and calcium silicate, which float to the top as a slag. 3. a) about 4% carbon. It makes the cast iron very hard, but very ...
A metal can be reduced by carbon if it is less reactive than carbon and so appears below carbon in the reactivity series. Using the reactivity series, can you name a metal that cannot be extracted from its ore using carbon? If a metal is more reactive than carbon, other chemical reactions and processes must be used in its extraction. Certain ...
Extraction of metals Ores. Some metals, typically the unreactive ones like gold, are found in the Earth's crust as pure elements. But most metals are found combined with other elements to form ...

The metal loses the oxygen, so it is reduced. The carbon gains oxygen, so it is oxidised. Reduction of iron is shown in the following chemical equation: iron oxide + carbon → iron + carbon dioxide . Heating coal in the absence of oxygen forms coke. This is used as a source of carbon for metal extraction.
