Why coke is used as reducing agent in the extraction of iron?

Explanation: Coke is a tough, porous and black substance. It is almost pure form of carbon. It is used as a reducing agent in the extraction of metals.

Why coke is used in extraction of metals?

Answer:The role of coke in the extraction of iron from its oxides is that it reduces the iron oxide to molten iron metal. Coke also when burnt in the blast furnace, supplies the heat required for carrying out the extraction of iron from its oxide.

Is coke used as a reducing agent in the extraction of metals?

Coke is one of the products of coal, which is mainly used as a reducing agent in the extraction of metals (like iron, zinc etc.) Coke is a tough and porous black solid substance Coke is prepared by heating coal in the absence of air.

Which is used as a reducing agent in the extraction of metal?

Answer : Coke is used as a reducing agent in the extraction of metals. It is used in the manufacture of steel and in the extraction of many metals.

How coke is used in manufacture of steel?

-Coke is supposed to be added to the blast furnace at the time of preparation of steel from iron. -When coke is used up it produces a high amount of heat and little smoke, making it is suitable for the smelting of steel. -Therefore coke is used in the manufacturing of Steel. So, the correct option is C.

Is coke used in manufacture of steel?

-Coke is supposed to be added to the blast furnace at the time of preparation of steel from iron. -When coke is used up it produces a high amount of heat and little smoke, making it is suitable for the smelting of steel. -Therefore coke is used in the manufacturing of Steel.

Is coke used in the production of steel?

Coke is used as a fuel and a reducing agent in melting iron ore. When coke is consumed it generates intense heat but little smoke, making it ideal for smelting iron and steel. Prior to the 1880’s, steel was produced using charcoal. By 1920, nearly 90\% of US steel was produced using coke.

Which metal is extracted from coal?

Extraction of iron from coal bottom ash by carbon reduction method.

What is used in the manufacture of steel and in the extraction of many metals?

Coke is a pure form of carbon. It is used in the manufacture of steel and in extraction of various metals.

What are the uses of coke?

Uses of Coke:

• The most common use of coke is as a fuel for stoves, furnaces and blacksmithing. It is sometimes preferred over coal because burning coke produces very little smoke.
• It is also used to produce iron in a blast furnace.
• Coke is used to manufacture steel and many other materials.

What is coke the mineral?

Coke is the non-volatile residue of the decomposition, the cemented-together carbon and mineral residue of the original coal particles in the form of a hard and somewhat glassy solid.

Why is carbon dioxide used as a reducing agent?

Carbon is a good reducing agent, especially at higher temperatures, because it is a non-metal and it combines with oxygen and forms its gaseous non-metallic oxides. Its dioxide CO2 being a gas, escapes away, hence it’s a good by-product as we don’t have to separate it further.

What are the ways to reduce metal oxides?

The Oxides of Metals like Zn, Fe, Cu, Ni, Sn and Pb are usually reduced by using carbon as reducing agent. In this process, coke is mixed with roasted ore and heated to a high temperature in a furnace. Coke reduces the metal oxides into free metal. For example, 3. Reduction by Aluminium (aluminotherapy)

What happens when we heat Fe2O3 ore with coke?

When we heat Fe2O3 ore with coke (C) at very high temperature (1400°C), carbon removes oxygen from iron oxide (reduction) in the form of CO and CO2 and hot liquid iron is obtained… This is how coke is used as reducing agent in extraction of metals. 8 clever moves when you have $1,000 in the bank.

What are the methods of reducing calcined or roasted ores?

The following methods are used for the reduction of calcined or roasted ores into the free metals. The carbon reduction process is also called smelting. The operation consists in the reduction of the oxide to the metal by strongly heating the ore with carbon in the form of coke or anthracite.
