  • Extraction of Iron Metallurgy Blast Furnace and Reactions

    13.07.2018· It is in the blast furnace that extraction of iron occurs. 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. A blast furnace is a gigantic, steel stack lined

  • Iron Extraction by Blast Furnace Metallurgy Procedure

    29.06.2020· Iron, when extracted from iron ore such as haematite containing iron(III) oxide, Fe 2 O 3, in a blast furnace is called iron extraction blast furnace metallurgy. In this reduction reaction, oxygen is removed from the iron(III) oxide to leave behind iron. Generally, the extraction of metals and their isolation are based on three major procedures. The steps are: 1. Concentration of Ore 2

  • Extraction of iron: The blast furnace Free ZIMSEC

    27.04.2016· Coke, limestone and iron ore are fed into the top of the furnace. Hot air is forced through tuyeres (openings) This burns the coke and in the process provide the heat required for the smelting process to take place. Near the base of the furnace the carbon in the coke combines with oxygen to give carbon monoxide.

  • blast furnace for extraction of iron theory

    27.12.2019· 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. In a blast furnace, fuel (coke), ores, and flux (limestone) are continuously supplied through the top of the furnace, while a hot blast of air
