What is the product obtained from blast furnace?

Detailed Solution. A blast furnace is a type of furnace which converts a mixture of metallic ore, coke, and flux into liquid metal by introducing air under high pressure. The product of blast furnace is pig iron which is an intermediate product in the production of steel. It is also called crude iron.

What metal is extracted by direct heating?

For metals lower than carbon in the reactivity series of metals, the extraction of the metal from its ore is through the reduction of its oxide with carbon. Extraction of the copper and mercury metals is done through direct heating of the metallic compounds.

Which raw material is used in making steel?

There are three main raw materials needed to make steel. Iron ore, coal and scrap steel.

How different metals are extracted?

There are 3 main methods of extracting metals from their ore. They are reduction of the ore with carbon, reduction of the molten ore by electrolysis, and reduction of the ore with a more reactive metal.

What is the name given to the iron obtained directly from the blast furnace?

Answer: The iron obtained from blast furnace contains 4% Carbon and many impurities like S, P, Si, and Mn in smaller amount and this iron is known as pig iron.

What is the name of furnace obtained cast iron?

A cupola or cupola furnace is a melting device used in foundries that can be used to melt cast iron, Ni-resist iron and some bronzes.

What type of furnace is used for smelting?

In modern copper smelting, a reverberatory furnace is used. Concentrated ore and a flux, commonly limestone, are charged into the top, and molten matte—a compound of copper, iron, and sulfur—and slag are drawn out at the bottom.

Why is iron extracted in a blast furnace?

The extraction of iron from its ore is a long and subdued process, that helps in separating the useful components from the waste materials such as slag. What happens in the Blast Furnace? The purpose of a Blast Furnace is to reduce the concentrated ore chemically to its liquid metal state.

Which metal Cannot be extracted by smelting?

(a) Aluminium cannot be extracted by the smelting process because : (i) Alis highly electropositive element and has strong affinity for oxygen.

Which metals are extracted by electrolysis?

Which is used for extraction of metals?

An ore is a mineral that contains enough metal to make it worth extracting the metal. Carbon can be used to extract metals from some metal oxides. A metal can either be reduced or oxidised in a reaction.

What is extraction of metal Class 10?

Conversion of metals ores into oxides: It is easy to obtain metals from their oxides. So, ores found in the form of sulphide and carbonates are first converted to their oxides by the process of roasting and calcination. Oxides of metals so obtained are converted into metals by the process of reduction.

Which metals can be extracted by heating with carbon?

Extraction by Heating with Carbon Some metals can be extracted by heating with carbon such as zinc, tin, lead, copper and iron from their corresponding oxides. Metals above zinc in the reactivity series are too reactive to be extracted by heat- ing with carbon or carbon monoxide gas.

How are metals like iron are extracted?

How are metals extracted using carbon?

If a metal is less reactive than carbon, it can be extracted from its oxide by heating with carbon. The carbon displaces the metal from the compound, and removes the oxygen from the oxide. This leaves the metal.

What is pig iron used for?

Pig iron is a solid form of hot metal, obtained from iron ore or scrap recycling, and it is processed with blast furnace or electric arc furnace. Pig iron is used as a raw material for iron steel making and most of this material was imported.

Which metal is used to make iron and steel?

The ores used in making iron and steel are iron oxides, which are compounds of iron and oxygen. The major iron oxide ores are hematite, which is the most plentiful, limonite, also called brown ore, taconite, and magnetite, a black ore.

How is iron ore extracted?

Most iron ores are extracted by surface mining. Some underground mines do exist, but, wherever possible, surface mining is preferred because it is cheaper.

Which furnace is used to produce pig iron?

Blast furnaces are used to produce pig iron from iron ore for subsequent processing into steel, and they are also employed in processing lead, copper, and other metals.

Which of the following ferrous material is made in cupola furnace?

Furnace TypeRaw MaterialsCupola FurnaceIron ore, scrap iron, lime, cokeElectric Arc FurnaceScrap iron, fluxInduction FurnaceScrap iron or non-ferrous metalsReverberatory, Hearth, or Crucible FurnaceNon-ferrous metals, flux

What is a cupola furnace used for?

cupola furnace, in steelmaking, a vertical cylindrical furnace used for melting iron either for casting or for charging in other furnaces. René-Antoine Ferchault de Réaumur built the first cupola furnace on record, in France, about 1720.

How steel is made in blast furnace?

To make steel, iron ore is first mined from the ground. It is then smelted in blast furnaces where the impurities are removed and carbon is added. … About halfway down, limestone begins to react with impurities in the ore and the coke to form a slag. Ash from the coke is absorbed by the slag.

What is metal slag?

Steel slag, a by-product of steel making, is produced during the separation of the molten steel from impurities in steel-making furnaces. The slag occurs as a molten liquid melt and is a complex solution of silicates and oxides that solidifies upon cooling.

How is steel made?

At the most basic, steel is made by mixing carbon and iron at very high temperatures (above 2600°F). Primary steelmaking creates steel from a product called “pig iron.” Pig iron is smelted iron, from ore, which contains more carbon than is correct for steel. … Oxidization removes excess carbon.

What is a metal furnace?

A metallurgical furnace, more commonly referred to as a furnace, is a device used to heat and melt metal ore to remove gangue, primarily in iron and steel production. … There are several different types of furnaces used in metallurgy to work with specific metal and ores.

How zinc is extracted?

Zinc is extracted from the purified zinc sulfate solution by electrowinning, which is a specialized form of electrolysis. The process works by passing an electric current through the solution in a series of cells. This causes the zinc to deposit on the cathodes (aluminium sheets) and oxygen to form at the anodes.

What are the raw materials used in the extraction of iron?

The raw materials used to produce pig iron in a blast furnace are iron ore, coke, sinter, and limestone. Iron ores are mainly iron oxides and include magnetite, hematite, limonite, and many other rocks.

What is Aluminium extraction?

Extraction of aluminium Aluminium ore is called bauxite . The bauxite is purified to produce aluminium oxide, a white powder from which aluminium can be extracted. The extraction is done by electrolysis. The ions in the aluminium oxide must be free to move so that electricity can pass through it.
