Question

what are the different furnaces used for extraction of metals?​

Answer 1

Explanation:

The difference furnaces used for extraction of metals are

Blast Furnace : A Blast Furnace is a type of metallurgical furnace used for smelting to produce industrial metals, generally pig iron, but also others such as lead or copper. Blast refers to the combustion air being "forced" or supplied above atmospheric pressure

Reverbatory Furnace : A reverberatory furnace is a metallurgical or process furnace that isolates the material being processed from contact with the fuel, but not from contact with combustion gases. The term reverberation is used here in a generic sense of rebounding or reflecting, not in the acoustic sense of echoing.

Bessemer Converter : The Bessemer process was the first inexpensive industrial process for the mass production of steel from molten pig iron before the development of the open hearth furnace. The key principle is removal of impurities from the iron by oxidation with air being blown through the molten iron. The oxidation also raises the temperature of the iron mass and keeps it molten.

Some other furnaces :

• puddling furnace
• open hearth furnace
• Basic oxygen furnace
• electric arc furnace
